According to Jack Ma, founder and executive chairman of the Alibaba Group

Don’t worry. Any mistake is a wonderful revenue for you.

So I tell myself, and told my young people. Before 20 years old, be a good student. When you do entrepreneur, just learn some experience.

Before 30 years old, follow somebody. Go to a small company. Normally in a big company it is good to learn processing. You are a part of a big machine. But when you go to small company you learn the passion, you learn the dreams. You learn how to do lot of things one time. So before 30 years old, it’s not which company you go, it’s which boss you follow. It’s very important. A good boss teach you, differently … and before from 30 to 40 years old you have to think very clearly … you’re working for yourself, if you really wanna be entrepreneur.

When you are 40 to 50 years old, you have to do all the things that you are good at. Don’t try to jump into the new area. It’s too late. You may be successful but the rate of dying is too big. So 40 to 50, think about … how can focus on things that you are good at.

But when you are 50 to 60 years old, work for the young people. Because young people can do better than you. So rely on them, invest on them, making sure they are good.

So when you are over 60 years old, spend time for yourself … on the beach, sunshine. Right? It’s too late for you to change, normally.

But I … this is my advice to the young people. 25 years old, make enough mistakes. Don’t worry. You fall, you stand up, you fall, you stand up. Enjoy it, at 25 years old, enjoy the show, enjoy the show.
