I know a lot of people in graduate school. Some of them are happy, some of them are miserable. Most are determined to finish no matter what. But that’s not always a good idea.
Grad school (and academia in general) is awful at allowing scientists to have a life outside of work. And when you’re in college and are good at science and like science, you don’t see many options for people who love science but don’t want to be scientists. Lady Quantum has had enough of that and is going on to other (way more awesome) things.
I say, good for her.
