Despite a desire to write that is older than memory, there have always been bits and pieces that I have found to be gaping black holes. Much of what you've talked about of your own process has helped me figure out what tools I need to bridge those holes. And of course, it's very cool to watch one of your friends become a Real Live Author right in front of you (gives hope to all of us peons out there, hoping to do the same, someday, maybe). No matter what: You've done it. Ergo, it can be done.
