Just do what I do. Split your time between kid(s), work, house projects, errands, and play a little of each backlogged game you have. Get absolutely nothing in your life done by trying to do everything 24/7. This way you get the benefit of feeling like you have no free time while also having the benefit of getting burnt out and overstressed. It can't backfire. 100% sustainable.

Roughly $200 a year. You can buy a very large external hard drive for that price...which would be a much better investment.
