Once you start getting really into your major, you don’t intersect with a lot of kids outside that general field. But I’m not sure it’s such a great thing to never interact in college with students who aren’t pretty much like you in terms of ambition and interests.
I had a parent conference today for a kid who is truly intellectually gifted. He turns it in when he wants but his grades are lackluster. He may end up being the smartest kid at the community college, but if you actually talk to him he’s brilliant, funny, interesting, and knows a lot about things most people don’t even know to think about.
