1. Social awkwardness - constantly meeting people and having the same mundane conversations is not only tiring, it is downright depressing. With time comes familiarity and the awkwardness noticeably dissipates.
2. Posturing - it is very hard to get to know anyone and very hard to let your own guard down when you are worried about preserving your personal "brand" as the aloof heir or the high-fashion financier or the plugged-in media guy. Again, time seems to break down personas into real people.
3. Support - there isn't any official support and it can be very isolating and lonely. By second quarter, genuine friends are there for you; plus, Stanford offers stellar back-up in the form of WIM groups, 2nd year coaches, and student activities.
4. Bubbly - first quarter at the GSB covers you in a hard plastic bubble that doesn't let in news from the outside world (say good-bye to all your favorite blogs), friends from the past (even ones who live in the Bay Area), or connections to long-term goals (the one downside of the exclusive academic period).
5. Misaligned expectations - classes and schoolwork are both valuable and time consuming. Don't expect anything else.
6. Herding - MBA1s are pack animals. There is tremendous tension for independent-minded adults to constantly follow the flock or risk feeling left out.
7. Email overload - it's truly overwhelming. It doesn't let up, but you get a bit better at managing it.
8. Weather - Kidding.
I'm sorry for the heaps of negativity in this post. I really am much happier this quarter. In recent news, I applied to a couple summer jobs through on-campus recruiting and have signed up to help manage two activities I think are interesting. I still struggle with the Sunday night blues, but it's not so bad.
