I'm doing a PhD in ethics. This means I spend a lot of time teaching undergrads things they already know, and thinking about questions that you have to be a little weird to find exciting.
When the academic life seems too daunting, I like to comfort myself by remembering that I've always got my fallback career of being a rock star. I play piano, guitar, bass, and make electronic music. Sadly I haven't won any awards for these musical ventures.
