I have wondered if anyone has advice on what an ideal pie chart of your discretionary time should look like. How much of my time should be spent learning new technical things, and of that how much should be directly applicable versus exploring related fields versus totally random, hoping for serendipitous connections. How much of my time should instead be spent on reading classic literature, building side projects, household chores such as tidying up, personal finance, watching tv and movies, playing video games, revisiting old journals of ideas, socializing, networking, etc. I'm sure if most people sat down and did a full accounting of how they spend their time, they'd feel guilty. We know we need rest, just not how much of it. Nor how to divide up the non-rest time optimally. It's not even clear what the objective function is. Happiness? Meaningfulness? Bank account? Reproductive success? I haven't dedicated enough of my pie to reading the thoughts of others on this subject.
