As Thomas Carlyle said: ＂genius is endless hardworking .＂ All the great achievements are industrious. Nobody can expect to do any great success if he didn't work hard. Take Newton whold life for example. Newton was interesting and energy on reading and studying, which became the main content of his life when he was young. After entering university in 1661, he diligently engaged in mathematics, physics, optics, chemistry, philosophy and other subjects. He studied extremely hard on Descartes' book called ＂geometry＂ until he himself became the owner of the book. His experience suggests that knowledge is achieved with diligence and hard work is the key to success.
