我不让任何人定义我。我自己定义自己。

做你自己，其他角色都已经有人扮演了。

In economics, the devil is often in the details.

Choose always the way that seems the best, however it may be; custom will soon render it easy and agreeable.

Happiness is a good flow of life； the conviction that you are taking part in the universe's purpose.

现在不是去想缺少什么的时候，该想一想凭现有的东西你能做什么。
