I declare: freedom is the ultimate goal of life.

民主是最坏的政府形式——除了其他所有不断地被试验过的政府形式之外。

I think it's important to have a strong work ethic and to be disciplined.

If you get up in the morning and think the future is going to be better, it is a bright day. Otherwise, it's not.

我倾向于认为相机比人眼可靠得多。

I'm not a genius, I just work harder than others.
