It's not enough to simply decide to keep up with "maintenance" and then do it, because if you are the type of person who lacks the discipline to stick to things, you will unconsciously resist any attempt at change. You need the ability to hack your habits. I've been trying Giles Bowkett's system for building habits based on the "calendar about nothing" for a couple weeks. It seems promising (for example, two weeks is longer than i usually stick to things), but it's too early to tell. I think the key is to change only one thing at a time, until the habit is locked in.
