急需一篇以“The key to the successful door”为题的英语演讲搞(演讲时间为五分钟)

Now I would like to talk something about the key to the successful door.

Some people think that success comes from diligence while others agree that success has no link with diligence. From my point of view,The key to the successful door is diligence . There are some reasons as follows.
Firstly, most people are biologically endowment with almost the same I.Q. , but some of them get success owing to some important reasons among which it is diligence. For instance, a chinese famous mathematician Chen Jinrun’s great achivements is his hard working on math.
Secondly, diligence may lead to success while laziness must result in failure. Success means that we fulfill a goal which is challenging、meaningful. If we can not try our best and be industrious to realize the goal, how can we get success?
Lastly, If people succeed, they must pay for their efforts and time. Naturally, they will not be satisfied and want to get hold of higher objectives so as to promote themselves in order to achieve their higher ranks or get more profits, etc. . Therefore, they will become more diligent to realize more success.
In a word, I hold the view that diligence is the key to the successful door.
