If you don’t mind being wrong on the way to being right you’ll learn a lot—and increase your effectiveness. But if you can’t tolerate being wrong, you won’t grow, you’ll make yourself and everyone around you miserable, and your work environment will be marked by petty backbiting and malevolent barbs rather than by a healthy, honest search for truth.

You must not let your need to be right be more important than your need to find out what’s true. Jeff Bezos described it well when he said, “You have to have a willingness to repeatedly fail. If you don’t have a willingness to fail, you’re going to have to be very careful not to invent.”

Fail well. Everyone fails. Anyone you see succeeding is only succeeding at the things you’re paying attention to—I guarantee they are also failing at lots of other things. The people I respect most are those who fail well. I respect them even more than those who succeed. That is because failing is a painful experience while succeeding is a joyous one, so it requires much more character to fail, change, and then succeed than to just succeed. People who are just succeeding must not be pushing their limits. Of course the worst are those who fail and don’t recognize it and don’t change.

Don’t feel bad about your mistakes or those of others. Love them! People typically feel bad about their mistakes because they think in a shortsighted way about the bad outcome and not about the evolutionary process of which mistakes are an integral part. I once had a ski instructor who had also given lessons to Michael Jordan, the greatest basketball player of all time. Jordan, he told me, reveled in his mistakes, seeing each of them as an opportunity to improve. He understood that mistakes are like those little puzzles that, when you solve them, give you a gem. Every mistake that you make and learn from will save you from thousands of similar mistakes in the future.

Don’t worry about looking good—worry about achieving your goals.
