参考作文地带整理勤奋英语作文范文：

Diligence is the key to success. It means persistent work and does not mean that we are to exhaust ourselves all day and night without any rest. The true meaning of diligence is the careful use of time for the purpose of self-improvement.
 
Many people strongly believe in luck, which is a serious mistake. If luck does exist, it will never fall upon lazy bones. There are also some people who think that they are far superior to others in intelligence and therefore, do not need to study hard. They are sure about their success, but too often they will be disappointed, as few of them can be successful only with their so-called cleverness.

In fact, time is always fleeting and can never be regained. The really clever people are those who understand the importance of diligence and make it their habit, These people are on the way to success by their own efforts.
