Are you getting enough sleep? I find that, after work, I don't really have the energy to do as much -- and certain things just seem completely unapproachable. But if I get a good night's sleep on Friday night, suddenly I have a little more interest on Saturday to tackle some of those projects. That tipped me off to a realization some years ago that maybe I just need to focus on keeping a good sleeping schedule. I quickly lose motivation if I'm even a little tired, and then all I want to do is consume. OK for playing games, not so great for finishing a project.

Time to move onto the next build.
