I love reading books, it's always been my favorite thing to do.  I think one of the reasons I love books so much is because you can escape into another world.  A happier world.  Same with writing.  I can write about whatever I want, I can dream whatever I want and I can write about things I want.  It makes me feel at peace when I write, so I write.  I write whatever comes to mind.  I always have stories running through my head so I am always jotting down little pieces of stories I might write some time.
