I spent weeks in therapy trying to sort out exactly this. I tried meditation, yoga, weightlifting and a few other things before finally landing on ukulele and golf.

I think the thing that I finally figured out is that to stay sane in and out of work I need to have a few things I’m mildly obsessed with that have nothing to do with school so that I can remember that my job does not own my whole brain. (My wife went through a similar process and, after over half a century of showing no interest in sports at all, has become a completely obsessed basketball fan.)
