Slightly irrelevant comment, but I studied Jazz at a good conservatoire, and after years as a pro musician, I ended up spending years as a pro software engineer. There is weirdly some cross-over, and that vocational drive is actually pretty handy for start-ups and things. I do think that technology is often vocational. It can be just a job, but from where I sit working in different startups, I think I thrive most off people for whom it is a vocation.
