Work on the house. I put up some new lighting fixtures, the eighth one in this house. Involved cutting the wall, re-routing and removing junction boxes, re framing a few walls and ceilings, and a lot of spackling. That will keep you busy and make the little woman happy aside from adding value to your home.
I also found that you can cut a temperpedic mattress down from a king to a queen, with a regular saw, "sharp saw". I had a spare and only the master bedroom had a king, so I cut it and it saved some bucks.
It doesn't always have to be guns to keep you busy, but I got this great idea for a false wall, while doing this, to store my AR, and 12 gauge, in plain sight. You would never see it, and in an emergency, you just push the wall, "on a push pull hinge" and there they are. I just have to line it with plastic sheeting.
