Lawyers are notoriously disorganized and relentlessly procrastinate. I recently adopted GTD and have found the sense of peace and mind-like-water that I longed for. Things get done; I hold others accountable for things I've delegated to them; I actually have more time.
This article was posted recently on the ABA's website. Whether through strict application of GTD or through some other process, it describes the level of calm that one lawyer attained and the benefits others see in being organized. If only we all saw the light.
