"Ein Buch zu schreiben ist wie eine Reise in ein unbekanntes Land."

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.

未说出口的往往比说出的更有力量。
