"Depend on yourself" is what nature says to every man. Parents can help you. Teachers can help you. Others still can help you. But all these only help you to help yourself.

There have been many great men in history. But many of them were very poor in childhood, and had no uncles, aunts or friends to help them. They couldn't depend on them for education. They saw how it was, and began to work with their efforts.

One of the most famous teachers in England used to tell his pupils, "I can't make worthy men of you, but I can help you make men of yourselves."

Some young men are not the best in anything, and they are to be pitied(值得同情的). They can never do things successfully if they don't see their weak points and change their courses(做法). They are nothing now, and will be nothing as long as they live if they don't follow the advice of their parents and teachers, and depend on their own efforts.
