"Too tired to learn new things and I need to recharge." This is the part where optimising for happiness kicks in. I was in a similar situation and it involved investing less energy in things I was doing to open up energy to learn music. Music probably won't help my career or physical fitness, but I'm gambling that it will pay off in happiness down the line.

Being able to play music / an instrument is certainly a great skill to have. Can´t do it myself, due to a shared flat, but a great thing to do!
