“Diligence is the mother of good luck，”as the saying goes, which means hard work and perseverance bring about fortune and success. However, it does not mean exerting oneself all day and night without rest, food or sleep.

　　From my point of view, diligence is of vital significance in one’ s life and career. There are some reasons as follows. Firstly, industrious spirit is an indispensable quality that makes a person stand out, as most people are biologically endowed with almost the same IQ. Secondly, diligence leads to accomplishments while laziness must result in failure. An idle man indulges himself in creature comforts. That he is doomed to failure is of no doubt. Lastly, diligence helps remove ignorance, overcome difficulties, and enlighten the mind.

　　Therefore, it can be said that being diligent costs nothing but is worthy of millions of dollars. All in all, I hold the view that diligence is crucial in one’ s life.
