One of the biggest mistakes a person can make is to try not to make mistakes． As you make decisions in your life， you will very likely make some mistakes． But making mistakes is a big part of how you gain （获得）experience．
A simple example．You do poorly on a test because you didn't study hard enough．One bad test is not the end of the world， but it can quickly teach you that if you don't study，you won't do well．
Mistakes sometimes lead to arguments（争论） between people， But if you learn to understand things from another person's point of view， you will be able to learn very quickly from the mistakes you make and the mistakes you think other people have made． You can turn mistakes into opportunities（机会）．
For example， if you learn to understand others' feelings and problems， you will understand the people you work with much better instead of getting angry． And you will leam to talk about problems and be more patient with people you don't agree with﹣a friend， or a mate in your workroom or company．
So next time you think you've made a mistake， stop and ask yourself what you've learned from it， and what you will do differently in the future．
Show me the person in the room who has made a lot of mistakes， and I'll show you the person who has probably learned a lot．
