1、幸福是简单的，无求而自得，做自己应该做的，却没有不断追求的疲惫。幸福是透明的，没有利益的阴影，没有在追逐中受尽折磨的叹息，只有在运转不息的规律中起起落落。如船行水，随势起伏。
2、智慧的代价是矛盾。这是人生对人生观开的玩笑。
Wisdom appears in contradiction to itself, which is a trick life plays on philosophy of life.
3、如果敌人让你生气，那说明你还没有胜他的把握。
It can be inferred that you lack confidence in a victory over your rivals from the fact that you''re irritable against them.
4、我不知道我现在做的哪些是对的，那些是错的，而当我终于老死的时候我才知道这些。所以我现在所能做的就是尽力做好每一件事，然后等待着老死。
Only till my natural death could I tell which of what I have been doing is right or wrong, so now I have to try to do well in everything, and then wait to die a natural death.
5、也许有些人很可恶，有些人很卑鄙。而当我设身为他想象的时候，我才知道：他比我还可怜。所以请原谅所有你见过的人，好人或者坏人。
Some may be wicked, and some may be despicable. Only when I put myself in their position did I know they are more miserable than I. So forgive all that you have met, no matter what kind of persons they are.
