Categories are a powerful tool for organizing any of the information you store in Entourage 2004—whether it’s email, contacts, appointments, or notes—but I think they really shine as a way to provide context for your task list. I use Categories almost synonymously with the idea of "contexts" that David Allen discusses in Getting Things Done—as a way to identify the location, conditions, tools, or focus needed to work on a given item. As I said the other day, I try to use my Categories to provide ready answers to the "How," "Where," and "When" of a given task as clearly and uniquely as is reasonable. You want to be analyzing and thinking about this stuff when you’re planning it, so you won’t have to process it again when it’s time to actually do it.

You know the drill--items that never or shouldn't find their way to a full post. Digital Chow Mein.

My theory is that the secret code for most self-improvement systems—from Getting Things Done through Biofeedback and the Atkins diet—is not hard to break; any idea that helps you to become more self-aware can usually help you to reach a goal or affect a favorable solution. That’s pretty much the entire bag of doughnuts right there.

Self-improvement juju works not because of magic beans or the stones in your soup pot; it works because a smart “system” can become a satisfying cipher for framing a problem and making yourself think about solutions in an ordered way. Systems help you minimize certain kinds of feedback while amplifying others.

Also, when you’ve undertaken most any kind of program, there’s usually a built-in incentive to watch for change, monitor growth, and iterate small improvements (think: morning weigh-in). While I don’t doubt that some systems empirically work better than others, I suspect that success with any of them has much to do with how we each think, behave, and respond to our environment.
