I'm deciding between two schools for a PhD in a biology umbrella program. Both schools are comparable in pretty much every way: both prestigious in the field, I am confident I could find research and a mentor that's a good fit, good funding, etc. Option A is close to home, which I didn't want because I've been trying to branch out. I want to live somewhere different for a while, as I stayed pretty close to home for undegrad. Option B is across the country, which would be an adventure like I want. I am leaning towards Option B, but I'm afraid to commit to B because I'm scared that I'll hate living there. Whereas A would be a safer choice because I already know that the lifestyle there agrees with me. If I picked A I would feel like I'm being a coward. I've heard different things about transferring schools, so if I decide to go to B I'd fear not only hating living there, but also that if I do hate it I'll be stuck there for roughly 6 years. But on the other hand I could love living there, but never know it if I don't give it a try. What should I do?
