Several years after receiving my M.A. in social science (interdisciplinary studies) I was an instructor at S.F. State University for a year, but then went back to designing automated machinery, and then tech writing, in Silicon Valley. I've always been more interested in political economics and what's going on behind the scenes in politics, than in mechanical engineering, and because of that I've rarely worked more than 8 months a year, devoting much of the rest of the year to reading and writing about that which interests me most.
