So we should learn how to learn at school.
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.
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.
