I’ve always liked Quadszilla over at SEO Black Hat, and some of his most recent posts are really good. This particular post is a great method for building a new habit. I use the exact same technique for keeping track of my cardio workouts. I’m really consistent with lifting, but cardio is harder to stick with. Having a calendar in your face with big red X’s is hard to argue with. I’m not a member of the private SEO forum but I have heard really good things if you’re into the forum thing.
