It's gonna take a lot more than one Sunday morning in your case.
There's where you're wrong - I've started working on an outline of what I need to cover the next time I go to confessional. A little confession, a little penance, and I'm good to go. It's been a while, though - so far the outline is up to 46 pages, single spaced. I'll probably be through with the outline and ready to start a rough draft pretty soon.
