思考就是将自己局限于一个单一的思想，有一天它会像世界天空中的一颗星星一样静止不动。

世界上发生的任何事情，其意义无非是某些极大或极小值。

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.

Do what you can, with what you have, where you are.

未来属于那些能够在盈利和可持续性之间取得平衡的人。
