I'm happy being an academic. I love the balance of teaching and research. I love the academic freedom and the flexibility I have in terms of my work time. At the same time, I hope I'd be brave enough to be able to make the switch to something else if the job no longer excites me.
I was at a birthday dinner for a friend last night and started chatting to someone I hadn't met before. I found out that he had previously worked in a circus, been a dancer in a night club, and is now working for a bank. That's quite a diverse career path!
