The past is never dead. It's not even past.

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.

We change our behavior when the pain of staying the same becomes greater than the pain of changing.

明智地思考却愚蠢地行动，这是人性。

最好的还在后头。
