We go to school for education. We learn Maths, English,Chinese, Physics and other subjects. School education is necessary and important. However, no one can learn everything from school. Even a very good teacher can not tell his students everything they want to know.
Edison didn't have much schooling, but he became a famous scientist. It doesn't mean that school education is not important.He knew how to learn new things by himself. As a matter of fact, many things can be learned outside school by the students themselves.
So we should learn how to learn by ourselves.
