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.

浅陋的人，不能和他谈论深奥的见解；愚蠢的人，不能和他谋划有智慧的事。井底之蛙，不能和它谈论东海的快乐。

Innovation is not just about new ideas, but about making them work.

我不是榜样，我只是我自己。
