I started writing when I was 13 years old. What I wrote then were stories straight from the heart on to the paper. Nothing much has changed there but only now I have realised importance of many things, re-writing, point of view and how the story is told matters the most.
We writers are always observing and imbibing. What you usually write is always what you have heard, watched or felt. And when you do that, it's not impossible to incorporate your real life in fiction stories. But it's only for the writer to know and not the readers :)
