I found that when I'm not hammering during the week, I get weak, spiritually. There is something about even the simplest projects with some hammering that will help us get through the week and weak periods. So, don't delay, go play, and I bet you, you will feel better. Or, take on a big project that will take up that spare time of yours thinking of how you are going to do that difficult bend or make a difficult tapered leg. Good luck.
