Mathematics is not a spectator sport. You have to do it to understand it.

你唯一应该试图超越的人就是昨天的自己。

对自己要求比别人期望的标准更高。永远不要为自己找借口。

When you are young spend at least 6 months to one year living as poor as you can， owning as little as you possibly can， eating beans and rice in a tiny room or tent， to experience what your “worst” lifestyle might be. That way any time you have to risk something in the future you won’t be afraid of the worst case scenario.

有趣的是，对你来说最重要的事情往往最难开口。

我不是榜样，我只是一个成功的人。
