Do something completely different. I've been having a lot of fun putting fibre up on poles for the last few years. It's rewarding in a way that software isn't. Software is all about worrying about the mistakes I've made or might have made, whereas building real world infrastructure has an actual "it's done" aspect to it that software never has that is incredibly satisfying. And it works! Well, until a drunk driver or a propane delivery takes out a couple of poles or spans of fibre in the middle of the night and you have to go do some emergency splicing in -25C weather.
