The only limit to our realization of tomorrow is our doubts of today.

Limiting beliefs are the prisons of the mind, and learning is the key to freedom.

You are never too old to set another goal or to dream a new dream.

A person must go through hard work to achieve something.

不管你有多少钱，世上只有两种人：一种是还幸存的，一种是已迷失的。

我不是一个退缩的人。
