It’s good to learn from your mistakes. It’s better to learn from other people’s mistakes.

Warren Buffet

In the last decade, I went from student to entrepreneur to freelancer to climbing the corporate ladder to blogger to teacher.

Yes, that’s not a normal career path, and it’s also not what I ever expected. But life hardly turns out the way you expect.

That’s because we’re only human—and humans make mistakes.

Recently, I received an email from a reader. He asked about my biggest career mistake, and that got me thinking. And writing. A lot. And after writing more than 2,000 words about my career mistakes, I thought: “Wow dude, you’ve made every single mistake you possibly could.”

Anyway, I’ve cut out the obvious stuff and made a list of my top 10 mistakes. I hope that one of the points is useful to you.

1. Assuming That Your Career Is Linear

That is, by far, the most important lesson I’ve learned.

First, I’ve learned that assumptions are always bad. We collectively assume a lot of things without ever asking or researching. One of those assumptions is that careers progress linearly. Who ever said that? When I think about it, I have no idea why I believed that in the first place.

It goes like this:

  • You get an education
  • Get an internship
  • Stay put for three years
  • Then try to become a low-level manager
  • After a few years you move up
  • And if you stall, you move to another company for a better paying position


  • You’re a freelancer
  • You start doing work for free
  • You keep doing that for years
  • You can’t make ends meet
  • You get a job
  • You quit your job because you hate it
  • You start charging for your work
  • And you increase your rate a little bit every year

Last one: you’re an entrepreneur, you start a business, you grow, you think you’re awesome, you spend more than you make, you try to get investors, they own you, and you mess up.

Again: Why do we do this? It’s so predictable. Life’s way too short for that boring stuff.

Accelerate your learning curve. Focus on value. Learn more, and earn more. Make leaps. And sometimes when you learn, you take a step back. But that’s fine, because you will earn more in the future.

In today’s economy, it’s more about what you have to offer. For the first time in history, a lot of companies (not all) don’t look at age, gender, race, degrees—they care about what you have to offer.

So offer some great work. How? Learn faster. Access to information has never been this easy. Use it.

2. Prioritizing Money

I’ve done this. And if you do it too, there are three things that can happen:

  1. You end up in a job you hate
  2. You become an aggressive money-oriented businessperson or freelancer
  3. You say yes to work that crushes your soul

There’s nothing wrong with those things, but they’re not sustainable. I’m not trying to stop you from earning some cash. But instead of focusing on money, why not focus on other things that are more fulfilling? Things like learning, experience, doing work that you are interested in, adding value to other people’s lives.

Will most people follow this advice? Probably not, because they can’t say no to money. There’s only one simple rule to money and freedom: Live beneath your means. And yes, that’s hard.

(If you want to know more about how you can train yourself not to depend on money, please read Seneca’s Letters From a Stoic. He writes about it a lot.)

3. Wasting Time

You won’t believe how many evenings and weekends I’ve lost by watching TV, going out, pointless shopping, or any other leisurely activity. Sure, entertainment is good, but you don’t have to relax every single free minute you have.

Look, this is your life, and this is your career. Take it seriously.

Can I ask you something? What’s your skill? What are you exceptional at?

If you don’t know the answer, it’s time to get down to it. Start learning, practicing, doing—and do something that turns you into an expert at something.

4. Choosing a Job Over an Industry

In the last decade, I’ve tried my luck in several industries, including hospitality, fashion, IT, and banking. But in recent years, I’ve only committed to consulting and education.

I wish I did that earlier. Hopping from industry to industry has huge costs. You have to learn the industry, market, people, unwritten rules, you name it.

Most people decide what they want to be (or they just roll into a profession), and then they try to find a job—they don’t care about the industry as long as it pays. Or, they want to be an entrepreneur or freelancer and they follow the money.

But that’s not an effective strategy in the long-term because you will never become an expert at something. Instead, pick one or two industries that you love, and commit to finding an opportunity there.

5. Getting Comfortable

“Ah, I’ve worked hard and now I’m good.” Think again. You’re never safe.

Life is a competition. The next person is waiting patiently until you mess up, and then he or she will swoop in and take your position.

Is that really true? Well, to be honest, I don’t know. But I sure like to think that’s the case.

Why? Because that keeps me on my toes. The last thing you want is to become comfortable in your career.

6. Not Asking for Things

Yes, you’re a nice person. We get it. But don’t be too nice.

Other people will take your spot, push you over, and you will end up with nothing. You don’t have to be a jerk. Just know that when you’re in business, it’s business. And everything is business: art, sports, media, work-relationships, colleagues.

If you want to get something, you have to ask for it. Want a raise? Ask. No one will give it to you. What did you expect? “Oh hey, you’re such an awesome person. Here’s a free bag of money.” That’s never going to happen.

7. Not Following Your Interests

There are two camps on this topic: people who say you should follow your passion, and people who say you shouldn’t.

The funny thing is, the people who say that you shouldn’t follow your passion didn’t follow their passion. Get it? Why on earth would they encourage others to follow their passion?

Now, I don’t really like the word passion—and I don’t like the whole discussion. But all I can say is this: Life is not infinite. Do you really want to spend your time doing something you hate?

8. Not Listening to People

When I got my master’s degree in business administration years ago, I thought I was the man. I didn’t listen to people who were more experienced than me. Big mistake.

Practice is different from books, I didn’t realize that at the time. Now I prefer to be humble and listen to everyone. Also, that means being willing to listen to people less experienced than me. They often have the best ideas.

9. Wanting Too Much Too Quickly

Even though your career doesn’t have to progress in a linear fashion, you can’t make giant leaps every single day. And in the beginning, I especially tried to move too fast.

But now, I’m more patient. Before I started blogging, I’d written hundreds of essays when I was getting my degrees, and not to forget two huge theses. And I’ve worked in the trenches of business and marketing for years before I started coaching and consulting. No one ever saw that part of my career. And that’s fine, because that’s how you learn.

10. Not Asking for Help

Maybe you’re too proud. Maybe you think people will believe that you’re stupid. Maybe you’re not raised that way. But if you don’t ask for help, one thing is for sure: You will never get it.

Almost everything in life is a team effort. Even if you work entirely for yourself, you still need people. And they need you.

The “self-made” success stories are all fake. Whenever you’re spreading too thin, reach out to others—to colleagues, partners, friends, family. They will help you, and if they don’t, they’re not your real friends.

This Is Your Career

Why not take it seriously? That’s one thing I didn’t do enough until a few years ago. I was too passive.

If you find yourself unhappy with your career, or how it’s progressing—change your path. That’s the only universal advice there is.

And do it today. You know why? If you don’t do it today, when will you?

You and I both know the answer to that.
