I don't think anything is unreasonable for anyone. Seriously. So far two doctors have told me I shouldn't be able to work full time at all, and yet here I am, working full time and keeping it together (most of the time I completely lose it when I have a break from work, like right now, and over spring break). So I say go for what you want. Know that yeah, it will be stressful, but you won't know if you can do it unless you try. I think some people set the bar too low for us.

Or maybe I set the bar too high for myself, I guess I'll find out. And you will too! Do what you love!
