One of my biggest gripes with Getting Things Done since I started trying to heed its sage wisdom in 2004 was once you make these lists, they are your new psychic hell. I have been experiencing that for a while now. Basically, you need to go through your inbox one item at a time and decide to do it if it takes less than 2 minutes, defer it, or delegate it. Delegation doesn’t really happen that often for personal lists, so you have a huge pile of “deferred” – a bunch of stuff that isn’t in your inbox because you’ve already looked at it, but you haven’t done it because it takes more than 2 minutes.
What the hell do you do with that stuff?
