I’ve been having this problem, too. I have two little ones (10 months and 3 years) and my wife works nights, so I get up at least 2x a night on average.
What works for ME is that I try to spend a minimum of 5 minutes in the garage when I get the time. Sometimes I just sweep, sometimes I rearrange a shelf, and sometimes I start a new project. The way I look at it is that you have to build up the energy and make it a habit to get to work on your time off. I’ve been doing this for two weeks and I already find myself going down to the garage rather than watching tv because I enjoy making progress. Even if I just rearrange my toolbox, it’s something that needed to get done.
