Thanks for the suggestion, I like this so far. My biggest beef with idonethis is the single check mark to indicate any activity whatsoever, making it less usable for tracking multiple goals.

Exactly. When I used this, I had some work and exercise-related positive goals, a multi-point goal (cooking, which I love but don't always make time for) and one negative line (caving in to the gaming addiction of the moment).

At some point I abandoned it, but I can't remember what caused me to break the habit. I might have more luck with an iPhone app that kept the chains in my face more often?
