If you've lived in Chicago, you may have developed a taste for deep-dish pizza.
If you've lived in North Dakota, you may have developed an appreciation for well-insulated parkas.
If you've lived in the corporate world, you may have developed an addiction to PowerPoint.
Guilty, your honor.*
To wit:

Over the course of the next year (few years, decade, whatever), I anticipate giving a variety of presentations. Some will be promotional, some will be educational, some will be humorous (I hope!). I may talk about the writing business or where my ideas come from or why all my time has been sucked away by the insidious Internet. Regardless of the topic, I want to be prepared.
So this is my strategy:
I'm going to create PowerPoint slides covering every possible topic I can think of. Then, for any particular presentation, I can mix and match the appropriate slides to put together something riveting. Need a presentation on snaring an agent? Pull out the "How to Write A Query" slides, complete with the photo of a rhinoceros (you need a thick skin to query, get it?). Going to give a presentation to my 6th grader's class? Pull out the "Hey, Look What Funny Things I Can Do with Photoshop!" slides.
So far, I've got about 50 slides done, on my way to several hundred (or more). Here are some broad topics I plan to cover (the list isn't all inclusive, but it's a start):
Craft
Publishing Business
Promotion
Industry News
My Background
My Writing Routine
Author Influences
Cool Research
Humor
Got any topics to add?
Know where I can get a projector, cheap?

*Of the PowerPoint addiction--I don't much like pizza (that cheese thing again) and I don't much like cold weather either.
