The biggest mistake people make in life is not trying to make a living at doing what they most enjoy.

To live our lives trying to avoid mistakes is one of the biggest mistakes we can make.

The biggest mistake we could ever make in our lives is to think we work for anybody but ourselves.

The greatest mistake you can make in life is to be continually fearing you will make one.

I think the most common mistake for humanity is believing you’re going to be made happy because of some external circumstance.

It is ignorance that causes most mistakes.

The greatest of all mistakes is to do nothing because you think you can only do a little.

One of the greatest problems people have with failure is that they are too quick to judge isolated situations in their lives and label them as failures. Instead, they need to keep the bigger picture in mind.

The greatest mistake we make is living in constant fear that we will make one.

The biggest mistake that you can make is to believe that you are working for somebody else. Job security is gone. The driving force of a career must come from the individual. Remember: Jobs are owned by the company, you own your career!

What’s the biggest mistake you’ve made in your life and how did you recover? I’ve made a class of mistakes I would summarize the same way. The mistakes were obvious only in hindsight through one exercise, which is asking yourself: when you’re thirty, what advice would you give your twenty-year-old self? And when you’re forty, what advice would you give your thirty-year-old self? (Maybe if you’re younger, you can do it by every five years.) Sit down and say, “Okay, 2007, what was I doing? How was I feeling? 2008, what was I doing? How was I feeling? 2009, what was I doing? How was I feeling?” Life is going to play out the way it’s going to play out. There will be some good and some bad. Most of it is actually just up to your interpretation. You’re born, you have a set of sensory experiences, and then you die. How you choose to interpret those experiences is up to you, and different people interpret them in different ways. Really, I wish I had done all of the same things, but with less emotion and less anger. The most celebrated example would be when I was younger, I started a company. This company did well, but I didn’t do well, so I sued some of the people involved. It was a good outcome for me in the end, and everything worked out okay, but there was a lot of angst and a lot of anger. Today, I wouldn’t have the angst and the anger. I would have just walked up to the people and said, “Look, this is what happened. This is what I’m going to do. This is how I’m going to do it. This is what’s fair. This is what’s not.

The first mistake is never the one that ruins you. It’s the spiral of repeated mistakes that follows.

The problem is not slipping up; the problem is thinking that if you can not do something perfectly, then you shouldn’t do it at all...

The greatest tragedy in life is not death but life without a purpose — life with the wrong priorities. Life’s greatest challenge is in knowing what to do. The greatest mistake in life is to be busy but not effective. Life’s greatest failure is to be successful in the wrong assignment. Success in life is measured by the effective use of one’s time.

You see, we are so afraid to fail, to make mistakes, not only in examinations but in life. To make a mistake is considered terrible because we will be criticized for it, somebody will scold us. But, after all, why should you not make a mistake? Are not all the people in the world making mistakes? And would the world cease to be in this horrible mess if you were never to make a mistake? If you are afraid of making mistakes you will never learn. The older people are making mistakes all the time, but they don’t want you to make mistakes, and thereby they smother your initiative. Why? Because they are afraid that by observing and questioning everything, by experimenting and making mistakes you may find out something for yourself and break away from the authority of your parents, of society, of tradition. That is why the ideal of success is held up for you to follow; and success, you will notice, is always in terms of respectability.
