One of the things I have been doing a little hit and miss now and then is working on writing some type of comprehensive story/novel/book.
My biggest problem is that I am (1) so all over the place with what interests me, and (2) I'm super fantastic with ideas - it's just the fleshing out the story part that stumps me every time.
I've got a friend from my old law firm that took some writing classes because she's interested in maybe putting out a book or seven in her lifetime. I sometimes send my initial drafts/outlines or first few chapters to her to get her feedback. She always comes back, "FINISH IT!!! I wanna know what happens!!"
Maybe being a voracious reader is not qualification enough to be an author.
