The Drawing Board...or the Drawing Room I haven't decided

I've been feeling creative lately. Feeling a little personally motivated. I've decided I want to write a book. I keep having all these thoughts/ideas about what I should write about. I've starting writing my autobiography about a million times and it never ends well. I've become so matter of fact about my life -- past and present. I don't know how it to tell it entertainingly. So I've settled on fiction. Just need to get an outline. need to get something down on paper (or on screen) any comments/suggestions are encouraged/appreciated.
