Writing Heroes

Its obvious that writers imput a bit of themselves into the characters they write.  You sort of create a world, where you can do things you can't in the real one, where in some kind of way there's a piece of you, or an alternate you succeeding where the real one didn't.  I intended to do this very thing for a novella, but have found there's always something of yourself you leave on the page.  There's always some kind of autobiographical tidbit sort of lurking in the pages.  I've been finding I'm writing about past experiences and things that interest me, and I'm getting more done than I ever have before.  I keep looking at what my interests are, or who I am, or things that happen to me, and I find I have more to write about.  Maybe in some wierd way its similar to how people can never stop talking about themselves, I'm writing instead.
