I really liked the idea of focusing on one thing for, hopefully, a long time to come. I also like the idea of a consistent lifestyle, as opposed to not really knowing where on the planet you're going to be at any given moment.
After I left college I thought, very naively, that either you became someone interesting - an artist - or you went into academia. If you ended up in an office you were dull and lacking. And I ended up in an office.
