Check out this thread for some great advice about writing a book:
http://www.sportsjournalists.com/forum/threads/36781/
I sent that link as well as one from a thread we had about writing screenplays to a friend of mine who has unsuccessfully been attempting to make a living as a novelist and screenwriter for years.
From what I have seen of the latest stuff he's sent me he hasn't been paying attention to this advice. He's been writing movies for a while now (he's dabbled in creating and writing for TV too) and it's always the same, dark, psycho-thriller stuff. Wooden characters, terrible dialogue, really formula stuff.
He'll bang out some screenplay in a couple of days, jam it into an envelope headed to a guy who he says is "repping" this stuff for him in Cali somewhere and move on to something else. Says he'll rewrite it when somebody pays him to do it. No surprise to me why he's never sold anything, I can't imagine anybody buying the stuff in the condition he sends it out in. He's always telling me that somebody from some studio or other is interested in this project or that, but they never fork over any cash, so I am hesitant to believe any of this ****.
As others have noted here, characters are everything. A while back my buddy tells me he is "developing" a one-hour TV drama based on a small music mag we all wrote for back in the late-80s. (It was an awesome time, even if it didn't last a year, man, it was so much fun.) Not a bad idea in the hands of someone who knew what they were doing, but he's been watching too many current dramas. There is the hard-to-deal-with genius with a deep, dark secret who is the focal point, the spunky single mom, the crazy boss, the serious co-workers and their whacky counterparts. Nothing we haven't seen before elsewhere.
I am sure anyone who has ever dabbled in writing has thought of writing a book. I know I have but I don't have the talent or discipline to pull it off and I have a ton of respect for those who can.
