A
“Depend on yourself” is what nature says to every man. Parents can help you. Teachers 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 boyhood, and had no uncles, aunts, or friends to help them. Schools were few and low. They could not depend on them for an education. They saw how it was, and set to work with all their strength to know something. They worked their own way up to fame.
One of the most famous teachers in England used to tell his pupils, “I cannot make worthy men of you, but I can help you make men of yourselves.”
Some young men have no ambitions(抱负) to do anything; and they are to be pitied. They can never succeed unless they see their foolishness, and change their courses. They are nothing now, and will be nothing as long as they live, unless they accept the advice of parents and teachers, and depend upon their own honest and serious efforts.
