I'm finding it increasingly difficult to pursue anything intellectually demanding outside of work. I used to be able to stay up late and immerse myself in whatever I was interested in, but can't seem to anymore. I still try and I'm always excited to sit down and dig in, but I find that I just don't have the mental energy anymore. I dunno if it's a function of age or my work getting more and more demanding over time. Sometimes I wonder if I ought to take a few-week staycation just to pursue my intellectual interests. Does anyone else relate to this? How do you manage to pursue subjects rigorously after feeling mentally drained by work and life?
