As the saying goes,if you have great talents,industry will improve them;if you have but moderate abilities,industry will supply their deficiency.This saying reflects the importance of diligence.The life of a lazy man is of no use to both himself and others.What’s worse,the man who is too lazy to work is more likely to beg or steal.Therefore,everyone should be diligent when he is young.

　　Diligence is the key to be useful. "Are frequently compensated with good training, a hard points to", only diligent, can get good grades.

　　From my point of view,diligence is of great significance in one’s life and career.The story of Hua LuoGeng is a case in point.Hua luogeng is due to the diligence, to become a famous mathematician.Hua luogeng in jintan county, home is very poor in childhood, dropping out of school at home, very early to help his father miscellaneous shop for a living, but he never give up the pursuit of mathematics. At eight o 'clock every night, go home after good accounts, to study their favorite mathematics, often study late into the night. In this way, day after day, year after year's efforts, hua luogeng finally got a chance to, when in tsinghua university math department assistant, he is very cherish the hard-won learning opportunities, he like a duck to water, swam in the sea of mathematics every day, give yourself only five or six hours of sleep time, it is really hard to believe. Hua luogeng even developed after lights out, also can the habit of reading. He, of course, there is no specific function, is just a kind of logical thinking activity of the mind. Under the lamp, he took a book and look at the topic to think for a moment, and turning in bed, close the meditation, start, to solve the problem in your mind run into difficulties, then turn off the bed, open the book for a while. In this way, a book can see ten days, he you can finish it 2 days, otherwise can't sleep. Hua luogeng who is considered the unusual assistant. After studying so hard to learn, later, became a famous mathematician.For example,Isaac Newton was often laughed at by others at primary school because of his poor performance in study,but he turned out to be a great physicist through his persistent hard work.

　　We learn from hua luogeng, in the later study, should be hard work, hard work, so as to achieve good results.
