Career advice from some of the world's most successful people

If clichés like "Follow your passion," "Give 110%," and "Be true to yourself" just aren't cutting it for you, then we've got some fresh takes on how to get a head start on your career.

From "Don't work too hard" to "Relax," here's some of the best — and often unconventional — advice for you from some really successful people:

Richard Branson: Never look back in regret — move on to the next thing

Richard Branson's mother taught him that.

"The amount of time people waste dwelling on failures, rather than putting that energy into another project, always amazes me," the Virgin Group founder and chairman toldThe Good Entrepreneur. "I have fun running ALL the Virgin businesses — so a setback is never a bad experience, just a learning curve."

Sheryl Sandberg: There is no straight path to where you are going

"As Pattie Sellers of Fortune Magazine says, careers are not ladders but jungle gyms,"the Facebook COO wrote on Quora. "You don't have to have it all figured out."

Sheryl Sandberg recommends having a long-term, abstract dream to work toward in addition to a more concrete 18-month plan. The long-term plan allows you to dream big while the short-term plan forces you to push yourself and think about how you want to get better over the next year and a half.

"Ask yourself how you can improve and what you're afraid to do," she said, adding "that's usually the thing you should try."

Warren Buffett: Exercise humility and restraint

In a 2010 interview with Yahoo, Berkshire Hathaway chairman and CEO Warren Buffett said that the best advice he ever received was from Berkshire Hathaway board of directors member Thomas Murphy. He told Buffett:

Never forget Warren, you can tell a guy to go to hell tomorrow — you don't give up the right. So just keep your mouth shut today, and see if you feel the same way tomorrow.

During this year's Berkshire Hathaway annual shareholders meeting, Buffett alsotold a curious seventh-grader that the key to making friends and getting along with coworkers is learning to change your behavior as you mature by emulating those you admire and adopting the qualities they possess.

Bill Gates: Keep things simple

In a 2009 interview with CNBC, Microsoft cofounder and chairman Bill Gates admired Warren Buffett's ability to keep things simple:

You look at his calendar, it's pretty simple. You talk to him about a case where he thinks a business is attractive, and he knows a few basic numbers and facts about it. And [if] it gets less complicated, he feels like then it's something he'll choose to invest in. He picks the things that he's got a model of, a model that really is predictive and that's going to continue to work over a long-term period. And so his ability to boil things down, to just work on the things that really count, to think through the basics — it's so amazing that he can do that. It's a special form of genius.

Ivanka Trump: Keep trying new things until you find something that sparks an interest — then do that

The executive vice president of development and acquisitions at The Trump Organization and head of the Ivanka Trumplifestyle brand tells Business Insider that you need to work especially hard early in your life to find and foster your passions so that you can love what you do.

"Passion is something that's hard to discover purely through introspection," she explains. "You have to have experiences — you have to learn real time and through experiences what makes you tick."

This means identifying the things that you could potentially be interested in and then just going for them, whether it's through internships or taking jobs in fields that could potentially be interesting for you.

"Just go out and do things, and those things that continue to spark an interest, do more of," she advises.

Once you've found your passion, the key to success is then putting in the work.

"The only people I've ever met who are really successful in their fields, regardless of what field that is, are people who are deeply passionate about the work they do every day and are motivated by a sense of purpose," Trump says.

Tony Robbins: Make yourself invaluable by learning the necessary skills you may be lacking

Before Robbins was the inspirational speaker with a cult following that he is today, his career was going nowhere even though he was putting in long hours.

It was his mentor the late motivational speaker Jim Rohn who gave him the advice that eventually helped him turn it all around. As Robbins detailed in a recent Facebook Live Q&A at Business Insider's New York office:

"He said, 'Tony, you're so focused on expecting things to happen so fast ... Your worth in the marketplace is based on your ability to add more value than anyone else. If you can find a way to do more for others in your company, more for the employees, more for the clients, than anybody else, your gifts will make room for you. But in order to do that, you've got to build skills.'"

Maya Angelou: Make your own path

In her book, "The Best Advice I Ever Got," Katie Couric quotes author, poet, dancer, actress, and singer Maya Angelou:

My paternal grandmother, Mrs. Annie Henderson, gave me advice that I have used for 65 years. She said, "If the world puts you on a road you do not like, if you look ahead and do not want that destination which is being offered and you look behind and you do not want to return to you place of departure, step off the road. Build yourself a new path."

Lloyd Blankfein: Chill out

The Goldman Sachs CEO's best career advice is something he says he'd never have followed himself when he was younger: "chill out."

He explains:

"There's not a sport — there's not an activity in life where, if you have a really hard grip, you actually are better. Whether it's baseball or golf … the looser you are, the further the thing goes, because it's a lot easier to whip around a string than a stick. If you're tight, I'm speaking metaphorically, if you're really tight you're not necessarily better."

J.K. Rowling: Embrace failure

J.K. Rowling, author of the best-selling children's book series "Harry Potter," knows a lot aboutachieving success — and failure.

"I don't think we talk about failure enough,"Rowling told Matt Lauer on NBC's "Today" show. "It would've really helped to have someone who had had a measure of success come say to me, 'You will fail. That's inevitable. It's what you do with it.'"

Before Rowling became one of thewealthiest women in the world, she was asingle mom living off welfare in the UK. She began writing about her now famous character, the young wizard, Harry Potter, in Edinburgh cafés, and received "loads" of rejections from book publishers when she first sent out the manuscript, The Guardian reports.

"An exceptionally short-lived marriage had imploded, and I was jobless, a lone parent, and as poor as it is possible to be in modern Britain, without being homeless ... By every usual standard, I was the biggest failure I knew," Rowling said during a 2008 Harvard University commencement speech.

She went on to say that she considered her early failure a "gift" that was "painfully won," since she gained valuable knowledge about herself and her relationships through the adversity.

Melanie Whelan: Get a job, any job

The CEO of SoulCycle believes that new college grads should forget about doing what they think is expected of them and just get to work.

"Get a job and work hard," she told The New York Times' Adam Bryant in an interview. "You are going to learn a ton in whatever that job is, so don't stress too much about what it is or where it is. Just take a job and put your head down, work hard, raise your hand for anything anybody asks you to do."

Melanie Whelan said it's important for young job seekers to live in the present rather than worry so much about where they're headed. The key is working as hard and learning as much as possible. When you do this, she said, good things will follow.

"A lot of people think in terms of 'should' — I 'should' be a banker, I 'should' go to law school, I 'should' pursue what I studied in school," she said.

This is a mistake, she told Bryant.

Eric Schmidt: Say yes to more things

In her book, "The Best Advice I Ever Got," Katie Couric quotes Google executive chairman Eric Schmidt as advising:

"Find a way to say yes to things. Say yes to invitations to a new country, say yes to meet new friends, say yes to learn something new. Yes is how you get your first job, and your next job, and your spouse, and even your kids."

Chelsea Handler: When you make a commitment, keep it

The millionaire comedian and actress says that she learned the importance of showing up when she was a waitress in her 20s.

"Whether that was a result of wanting to be liked from years of rejection in high school, or whether it was wanting to be dependable and reliable after years of being the opposite, I just wanted people to feel that they could count on me," she writes in a LinkedIn post, titled "I Used to Hate Doing Stand Up. Then I Discovered the Power of Showing Up."

Handler says that her habit for dependability has since bled into every facet of her life.

"It was no longer an option to not show up. I now practice 'showing up' with everything I do. It has permeated every facet of my life. Whether it's wanting to cancel a workout, a friend's party, a public appearance, my family in New Jersey. Whatever it is, when I commit, I show up," she says.

Marissa Mayer: Pick something and make it great

In a 2011 interview with the SocialTimes, current Yahoo president and CEO Marissa Mayer revealed the best advice she ever received:

" friend Andre said to me, 'You know, Marissa, you're putting a lot of pressure on yourself to pick the right choice, and I've gotta be honest: That's not what I see here. I see a bunch of good choices, and there's the one that you pick and make great.' I think that's one of the best pieces of advice I've ever gotten."

Steve Jobs: Don't just follow your passion, but something larger than yourself

In a Business Insider article, Cal Newport, author of "So Good They Can't Ignore You," referenced Steve Jobs biographer Walter Isaacson, who recalled an exchange he had with Jobs shortly before he died.

Jobs reportedly told Isaacson:

"Yeah, we're always talking about following your passion, but we're all part of the flow of history ... you've got to put something back into the flow of history that's going to help your community, help other people ... so that 20, 30, 40 years from now ... people will say, this person didn't just have a passion, he cared about making something that other people could benefit from."

Suze Orman: With success comes unhelpful criticism — ignore it

In a LinkedIn article about the best advice she ever received, motivational speaker, author, and CNBC host Suze Orman wrote that success has often made her a target of nasty criticism"entirely disconnected from facts." At first these attacks made her angry, but she eventually learned to ignore them.

She wrote:

"A wise teacher from India shared this insight: The elephant keeps walking as the dogs keep barking. The sad fact is that we all have to navigate our way around the dogs in our career: external critics, competitors, horrible bosses, or colleagues who undermine. Based on my experience, I would advise you to prepare for the yapping to increase along with your success."

Arianna Huffington: Don't work too hard

In a LinkedIn post last year, The Huffington Post cofounder Arianna Huffington revealed that she's often asked if young people pursuing their dreams should burn the candle at both ends.

"This couldn't be less true," she writes. "And for far too long, we have been operating under a collective delusion that burning out is the necessary price for achieving success."

She says that she wishes she could go back and tell her younger self, "Arianna, your performance will actually improve if you can commit to not only working hard but also unplugging, recharging, and renewing yourself."

Stewart Butterfield: Have an "experimental attitude"

Stewart Butterfield, cofounder of Flickr and chief executive of Slack, one of the fastest-growing business apps of all time, shared his best advice for young people with Adam Bryant of The New York Times:

"Some people will know exactly what they want to do at a very young age, but the odds are low," he said. "I feel like people in their early- to mid-20s are very earnest. They're very serious, and they want to feel like they've accomplished a lot at a very young age rather than just trying to figure stuff out. So I try to push them toward a more experimental attitude."

Dr. Phil McGraw: Make sure you'd be all right with someone judging you on any of your work

The television personality, author, psychologist, and host of the "Dr. Phil" show suggests that, before you submit any work, you should ask yourself if you'd be OK with it being the only thing someone used to form an opinion of you.

He tells Business Insider that he learned this lesson during the second season of his show, when he was having trouble deciding if he should cover a particular topic for an episode.

His son said to him: "You have to ask yourself this question: 'If someone is only ever going to see one Dr. Phil episode in their life, would you be OK with it being this one?' If the answer is 'no,' don't do it.'"

McGraw says that he keeps this in mind now with all of his work, whether it's a book he's writing, an answer he gives in an interview, or an episode he does.

George Stephanopoulos: Relax

"Almost nothing you're worried about today will define your tomorrow," "Good Morning America" coanchor George Stephanopoulostold personal-finance website NerdWallet. "Down the road, don't be afraid to take a pay cut to follow your passion. But do stash a few bucks in a 401(k) now."

Marla Malcolm Beck: Remember that you won't end up where you start

Marla Malcolm Beck, CEO of Bluemercury,said in an interview with Adam Bryant of The New York Times that she always reminds students that "nobody ends up in the first job they choose out of college, so just find something that is interesting to you, because you tend to excel at things you're interested in. But just go do it. You have nothing to lose."

Her other piece of advice: Go into tech.

"If you look at all the skill sets companies need, they involve a comfort level with technology," she told Bryant.

T.J. Miller: Work harder than anyone else around you

T.J. Miller, comedian and star of HBO's "Silicon Valley," told personal-finance website NerdWallet that this is truly the formula to success: "It worked for me, and I have mediocre talent and a horse jaw."

Alexa von Tobel: Get up, dress up, and show up

What Alexa von Tobel, founder and CEO of LearnVest and the author of New York Times best-seller "Financially Fearless," means is that it's important to wake up excited for what's coming, dress the part, and always show up ready to go.

She wrote in an article for Business Insider:

As a new hire, you will likely find yourself in tons of new situations, and it's up to you to figure out how to navigate them.

Remember that your manager is strapped for time, so know when to ask questions. Are you unsure of the objectives for an assignment? Asking her to clarify is crucial, since it's pretty hard to make the mark if you don't know where it even lies.

On the flip side, avoid bombarding your manager with petty questions that could be answered by your peers or a quick Google search.

Mark Bartels: Map out a timeline for yourself when you start a new job

"We talk about budgets; we talk about planning your finances; but what a lot of people don't do is plan out the next 12 to 18 or 24 months of their careers,"StumbleUpon CEO Mark Bartelstold Business Insider.

He said that a lack of planning can be costly, professionally and existentially, while having an agenda provides a metric for evaluating your success.

Hermione Way: Start your own business

"There has never been an easier time to start a business," Hermione Way, founder of WayMedia and star of Bravo's "Start-Ups: Silicon Valley," told personal-finance website NerdWallet. "There are so many free online tools. Just start, and if you fail you can always go and get a normal job, but you will learn so much along the way it will be a great experience."

John Chen: Being a "superstar" can hurt your career

"Most employees think that the best way to show value to their boss and get promoted is to aggressively claim credit and ownership over everything they do," BlackBerry CEO John Chen wrote in a LinkedIn post earlier this year. "While it's important to be recognized for what you do and the value you add, grabbing the glory is going to turn off your coworkers."

It can also turn off your boss, he warns.

"Trying too hard to show you're a superstar tells me that you only care about what's best for you, and not the company as a whole," he says.

Salli Setta: Never eat lunch alone

Red Lobster president Salli Setta tells Business Insider that it's important to get out from behind your screen at lunchtime because lunch is a prime networking opportunity.

The benefit of always having lunch plans with someone are twofold: You can get information that will help you "think about your job differently," and you also get on your companion's radar.

"It isn't about saying 'hi, what are we going to talk about, let's talk about sports,'" Setta says. "It's about identifying the object of this lunch in your mind" and going in armed with "a couple of things that you want to ask, and a couple of things you want to share."

Deepak Chopra: Embrace the wisdom of uncertainty

In a LinkedIn post last year, Deepak Chopra, popular author and founder of The Chopra Foundation, said that he wished he embraced the wisdom of uncertainty at a younger age.

"At the outset of my medical career, I had the security of knowing exactly where I was headed,"he wrote. "Yet what I didn't count on was the uncertainty of life, and what uncertainty can do to a person."

"If only I knew then, as I know now, that there is wisdom in uncertainty — it opens a door to the unknown, and only from the unknown can life be renewed constantly," he wrote.

Brian Chesky: Don't listen to your parents

Brian Chesky, CEO of Airbnb, said in an interview with The New York Times' Adam Bryant that recent grads shouldn't listen to their parents.

He told Bryant:

They're the most important relationships in your life, but you should never take your parents' career advice, and I'm using parents as a proxy for all the pressures in the world. I also say that whatever career you're in, assume it's going to be a massive failure. That way, you're not making decisions based on success, money and career. You're only making it based on doing what you love.

Diane von Furstenberg: Keep it real

In an interview with Adam Bryant of The New York Times, fashion designer Diane von Furstenberg says that she has learned that trusting yourself is the key to success.

"In order to trust yourself, you have to have a relationship with yourself," she told Bryant. "In order to have a relationship with yourself, you have to be hard on yourself, and not be delusional."

Rick Goings: Be nice to everyone

Rick Goings, CEO of home-products company Tupperware Brands shared his favorite pearls of wisdom for young people with Business Insider. One of them was to be nice to everyone when you go on a job interview.
