Yes... it's Behaviors + Tools. And it can take some time to work out the kinks to make a particular system work for you. But if we can learn from others who have used the same tools, we'll all make progress faster together.

This gives me an idea that maybe it would be helpful to start a thread for each organizing tool, and then people who are considering tools can weigh pros and cons of each, and also get tips on how to use them better. I'll start the OmniFocus thread, and others can start threads for the ones they're using, or chime in if someone else has already started one.
