生活充满不确定性，而这正是它有趣的地方。

如果你的艺术不能挑战你自己，它也无法挑战他人。

The truth is, the science of Nature has been already too long made only a work of the brain and the fancy: It is now high time that it should return to the plainness and soundness of observations on material and obvious things.

In this business, by the time you realize you're in trouble, it's too late to save yourself. Unless you're running scared all the time, you're gone.

去做高尚的事情，不要整天只是做梦。
