I'm reading a book that was given to be by a friend called Blue Like Jazz by Donald Miller. Here's a quote from the book that really hit me like a ton of bricks:

We live for what we believe. If I live what I believe, then I don't believe very many noble things. My life testifies that the first thing I believe is that I am the most important person in the world. My life testifies to this because I care more about my food and shelter and happiness than about anybody else. http://www.mikecolon.net/blog/2008/04/blue-like-jazz.html
