If you fail, don't forget to learn your lesson.
如果你失败了，千万别忘了汲取教训。
Frankly speaking, it is easy to talk about these things and they always sound good on paper, but it is somewhat difficult for us to incorporate these things into our daily life.

They say that history is written by the victors.
人们说历史是由胜利者书写的。
The hisory is always written by the victors, and by those who managed to survive.
If you can survive others a little long, you will have the time and the chances to change the history, at least you can decide what the later generations can see and leave some riddles for the later historians.
That sounds very good.
But the precondition is to survive and become a victor.
