From comments on a post elsenet: "If I'd wanted to stay in business programming, I wouldn't have hung on the World-Tree a.k.a. grad school for nine years, a sacrifice of myself to myself. And my eye-socket itches."
Poetic license now that I think about it carefully: it was actually *eleven* years. But three of those years were part-time, so it kind of works if you turn your head sideways and squint. Anyway, I like the flavor of the classics.
