I've made a concerted effort to consume less "junk media" in the last couple of years. In that time I've gotten an Amateur radio licence, I've built a couple of keyboards and speakers, I've started golfing (after a 20 year hiatus), I've learned to bake bread (from scratch, including grinding wheat!), I've read a lot of novels, and I'm happier for all of it.
