沉默是一种美德，但在喜欢的人面前沉默，就是一种懦弱。

The more you give, the more you get.

Courage consists not in hazarding without fear； but being resolutely minded in a just cause.

数学之美在于它是人类少数几个可以知晓绝对真理的领域之一。

I think we have been through a period where too many people have been given to understand that if they have a problem, it's the government's job to cope with it. 'I have a problem, I'll get a grant.' 'I'm homeless, the government must house me.' They're casting their problem on society. And, you know, there is no such thing as society. There are individual men and women, and there are families. And no government can do anything except through people, and people must look to themselves first. It's our duty to look after ourselves and then, also to look after our neighbour. People have got the entitlements too much in mind, without the obligations.
