Things that have changed the way you see the world
By "things" I mean art, movies, music, books etc., stuff with meaning. Not "Farcry changed my life. Seriously, I was a crack-smoking alcoholic with cancer until I found that game. It turned me around (sobs)"
I think for me the Sandman graphic novel changed the way I think about things more than anything else. Yes its a comic, but not some Marvel crap, its deeper and smarter than most novels even. It made me think about my ideas, and what I wanted to do with my life. It made me want to be a writer myself more than ever.
Laugh if you like, but go read it yourself, and be amazed.
Um, yeah I'm starting to sound like I'm hired by the guy. Anyone else read or seen anything that changed them?
