I don't believe in pessimism. If something doesn't come up the way you want, forge ahead. If you think it's going to rain, it will.

I'll do whatever it takes to win games,whether it's sitting on a bench waving a towel,handing a cup of water to a teammate.

Success is not final, failure is not fatal: It is the courage to continue that counts.

You have to spend some energy and effort to see the beauty of math.

The only freedom which deserves the name is that of pursuing our own good in our way， so long as we do not attempt to deprive others of theirs or impede their efforts to obtain it.

We have to be prepared to take some risks, but they must be calculated risks.

命名某物就是让它存在，给它一个在世界上的位置。
