Every man is his own greatest enemy， and as it were his own murderer.

A creative man is motivated by the desire to achieve, not by the desire to beat others.

Less is more.

我们必须接受事物的本来面目，但我们应该努力使它们按照我们希望的方式到来。

You have to have confidence in your ability, and then be tough enough to follow through.

数学是上帝用来书写宇宙的语言。
