"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 people only help you to help yourself. There have been many great men in history. Many of them were very poor in childhood, and had no uncles, aunts or friends to help them. Schools were few and not very good. They could not depend upon them for education. They saw how it was, and set to work with all their strength ( 气力 ) to know something. They worked their own way till they became well-known. One of the most famous teachers in England used to tell his pupils, "I cannot make worthy ( 富有的 ) men of you, but I can help make men of yourselves." Some young men don't try their best to make themselves valuable ( 有价值 ) to the human beings. They cannot gain achievements ( 成就 ) unless they see their weak points and change their course. They are nothing now, and will be nothing as they live, unless they accept the advice of their parents and teachers, and depend on their own efforts ( 努力 ).
