The world is full of obvious things which nobody by any chance ever observes.

心灵不是印象的被动接受者，而是感知过程中的积极参与者。

In the state of nature, profit is the measure of right.

The only thing that separates successful people from the ones who aren't is the willingness to work hard.

我不是一个放弃自己价值的人。

The world is what it is; men who are nothing, who allow themselves to become nothing, have no place in it.

You are always a valuable, worthwhile human being — not because anybody says so, not because you're successful, not because you make a lot of money — but because you decide to believe it and for no other reason.
