Who can learn everything from school?

So, many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, can’t teach his students everything that they want to know. His job is showing his students how to learn. He teaches them how to read and how to think. Much more is to be learned outside school by the students themselves.
   Great scientists, such as Newton, Galileo and Einstein, didn’t get everything from school, but they were all successful. They invented many things. The reason for their success is that they knew how to study. In other words, they knew how to use their brains. They read books that were not taught at school and they worked hard all their lives.
