"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 when they were young, 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 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 men of you, but I can help make men of yourselves. "
Some young men do not try their best to make themselves valuable to society. They can never gain achievements unless they see their weak points and keep improving themselves. They are nothing now and will be nothing as long as they live, unless they accept the advice of their parents and teachers, and depend on their own efforts.
