Appreciate the process of competing. It’s not just about winning or losing, but about respecting your opponents and the game.

最美的风景在攀登最艰难的山峰之后。

做善事容易，做了善事而逃避好名声就难了；不触犯他人容易，触犯了他人心里不计较就难了。为人处世，遇到有人对我蛮横无理，就要像走在灌木草丛中一样，荆棘挂住了衣服，只能缓慢前行小心地拨开荆棘就是了，荆棘也不是存心阻人啊！这样一来便能做到心中不劳累，而化解仇怨。

我对愚蠢的人有极大的信心；我的朋友们称之为自信。
