You’re alive, Bod. That means you have infinite potential. You can do anything, make anything, dream anything. If you change the world, the world will change. Potential. Once you’re dead, it’s gone. Over. You’ve made what you’ve made, dreamed your dream, written your name. You may be buried here, you may even walk. But that potential is finished.
The Graveyard Book, Neil Gaiman, 2010, 179
Got to be my favorite quote in the book!
