This. I have 2 kids, ages 6 and 9, and there's always something to do (help with homework, help with piano, take to soccer, make a cake from scratch together, etc). When everyone's asleep, that's when I work on my side projects. If I'm lucky, I get 2-3 solid hours before my body physically shuts down. I made a decision years ago to do away with tv, video games, etc during "me time," and instead work on projects / catch-up on reading. It's about slow, steady progress. It might take me a month to crank-out what amounts to be 10-hrs worth of work, but, in the end, it gives me more happiness than if I spent that month on tv.
