Kobe Bryant can be a good case of how diligence works in our life. When asked by one of his friends that what is the secret of his success, he replied with humor and implication that，Do you know how Los Angelos looks like at 4 oclock AM ? I know.Obviously, how could he, one of the greatest basketball players throughout the history of mankind who was once deemed not appropriate for playing basketball, have achieved unprecedented success in NBA without diligence ?

　　科比.布莱恩特是一个证明勤奋是如何起作用的很好的例子。当被他的一个好朋友问到他成功的秘诀的时候，他幽默而又意义深远地回答到：你知道洛杉矶凌晨四点的样子吗?我知道。很明显，这位曾经被认为不太适合打篮球的、人类历史上最伟大的篮球运动员之一的科比，如果没有勤奋的话，怎么可能在美职篮获得史无前例的成功呢?
