The Jeffery Deaver interview in Author Magazine had a few more tidbits I'd like to share. Admittedly, Deaver has a predictable writing style (e.g. figure out the least likely individual in the entire novel to have committed the crime, and you've solved the case), but his Lincoln Rhyme books are always a fast read and a ton of fun.
Besides -- as far as advice goes -- if you hear enough people say exactly the same thing, you start to take notice. And when someone throws in an oddball, you sit up and think, Hey, that's different. I wonder how that might work. Anyway, here's what Deaver had to say:
1. Study the market place. Write what comes out of your heart w/ the caveat of knowing where it fits into the market place.
2. Study the books of your favorite authors. Take them apart. Analyze them. Outline them. Copy down passages of writing that resonate with you.
3. Get an agent. They are a must in this day and age.
4. Figure out that rejection is simply a part of the game. It's a speed bump; it's not a brick wall.
