Have you been happy at Harvard? Does it ever feel too impersonal? Do you feel like it's especially difficult to establish relationships with professors? How are the other students on the whole? Was it difficult to find a social niche? And is winter substantially worse than winter in New Haven?
Yeah, I've been pretty happy and had a lot of fun. I don't think it's too impersonal...professors get budgets to take students out to lunch/dinner in small groups (6-10) students, so you do get to interact closely with profs. Just sign up for a lunch/dinner. When I wanted to meet with my civ pro professor to get advice on an actual lawsuit I'm involved in (merely as a class-action plaintiff--I had nothing to do with initiating the litigation), she was very accomodating and helpful.
Social niche, I guess that's up to the individual...I was ok finding one, although it wasn't super easy. But I think some people just instantly fit in with a group. So I'm not sure. But everyone in my section is quite friendly if you approach them--just not everyone is outgoing.
And the winters are a little better than in New Haven, actually. The avg. temperature is a few (like 3) degrees warmer in Boston in the winter.
However, New Haven is MUCH better than Cambridge at plowing snow during/after storms. So if you come to Harvard, bring boots.
