Student period is the start of one's life. All of us need to keep studying. When we are students, the point of what we are learning is not the knowledge itself, but the way discovering the world. After graduation, we begin to discover and learn. There is much to learn. How to communicate with others? How to lead your team to reach the goal? How to plan a trip? How to cook a great meal? We know so little about he world that we have to study every time.
Unfortunately, many people think they have learn all of the things in school. They are used to know the world by their experience learnt in school, and refuse to change their mind. It is a kind of arrogent.
