Constantly. I considered shepherding. (Seriously.) I spent some time on a farm during lambing season, which is busy, and I enjoyed it. But it's incredibly hard work, and you really have to be 100% dedicated to it. Plus I like traveling, and it's extremely difficult to leave a flock for any appreciable amount of time.

I've thought about teaching (programming) too. My dad is a retired professor, and I entertain no delusions of present-day teaching careers being anything like those of his generation. Still, there's something appealing about even just teaching as an adjunct once I no longer really need the money.
