The world is full of stories, but it's the ones we tell ourselves that shape our reality.

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.

数学中的每个问题都有解决方案；你只需要找到正确的路径。

自信是一切的关键。
