You\'ve overcome my biggest problem area, which is getting my lazy rump into the paint room.

And the tidiness will help in the end, but definitely sounds like it\'s time to stop cleaning! Some possible ideas:
Find out if you have a local store with a paint night. If you do, go to it. Hanging out with other mini painting fans and just slapping paint on a mini for a few hours might be a more congenial atmosphere to start back up. Or if you have a child in your life, take this opportunity to show them a little bit about the hobby and sit and paint with them for a few hours.
Work on some terrain, accessories or bases.
Pick something basic and fun with the goal of painting it within a few hours - a wolf or whatever to just basecoat, wash and drybrush up and boom it\'s done.
Paint something for someone else. A mini exchange, something you\'ve always meant to do as a gift for a friend, something Dragonreach told your wife to tell you to paint, whatever. ;-> Knowing that someone else is relying on you for something can sometimes be more motivation than completely self-set goals.
In a similar vein, paint something for a contest with a deadline. April 29 is the deadline for the new Chick Challenge, May 1 is the deadline for the Black Scorpion single fig contest and there are probably some others I\'m forgetting about. PP has one going right now too I think. I can probably find you websites with rules and such if you\'re interested in any of those.
