我不数我的仰卧起坐。只有当它开始疼的时候，我才开始数。

I have self-doubt. I have insecurity. I have fear of failure. I have nights when I show up at the arena and I’m like, “My back hurts, my feet hurt, my knees hurt. I don’t have it. I just want to chill.” We all have self-doubt. You don’t deny it, but you also don’t capitulate to it. You embrace it.

Life is too short to be living somebody else's dream.

The advancement of mathematics is due to those who are driven not by the desire for application but by the joy of discovery.

我尝试从每种情况中学习，无论是积极的还是消极的。
