I keep saying I want a PhD in biochemistry, and it's actually true. I like science and am perfectly functional in it, despite the fact it's not really where my talents lie.* I always assumed I wasn't interested in medicine, but now that I have some fascinating medical problems, I may have changed my mind. I've been thinking lately about how I would probably enjoy epidemiology.
If I'm going to play to my strengths, I really am interested in quantitative aspects of political science, in the same way that I'm interested in how "Wash your hands!" posters actually affect virus transmission rates.
*I'm good at writing and passionate about politics, neither of which dispose one to being really good at titrating things.
