5 Profound Book Quotes

I read for fun. I read to escape reality, but sometimes an author pen's a line that just sticks with me. Sometimes, I stumble across something so profound it follows me out of the fantasy world within the novel I'm reading and into the real world. The following are five quotes that not only have stuck with me, but have changed how I look at the world.
