My absolute favourite author:

“Morpheus: It is sometimes a mistake to climb. It is always a mistake never even to make the attempt... If you do not climb you will not fall. This is true. But is it that bad to fall, that hard to fall? Sometimes you wake, and sometimes, yes, you die. But there is a third alternative."

Todd, upon waking: "Sometimes you wake up. Sometimes the fall kills you. And sometimes, when you fall...you fly.” Neil Gaiman, Sandman

I read that when I was around 21/22 and it hit me hard because I would often let fear stop me from doing things.
