Building up a good friends list and joining a good country club will go a long way in alleviating your problems. If you have lots of green lights showing and play with those people you won't get quitters.
This is the first thing I thought of when I read the thread title.
I friend the players I had a good time playing against and look to play my friends first when looking for a multi-player game.
Oh, and I finish everything I start, well just about. In my 6 months playing virtually every day, I think I've quit twice. And always a solo game. I don't start multi-player games when there's a chance I'll be interrupted and I would never even think of quitting one otherwise.
My guess is the the type of people who quit games are the same people who yell "Get in the hole" at a real golf tournament. No class and no respect for the game.
