I feel similarly, OP. Without a goal in mind, I'm taking time off from university. But, I discovered the shallowness, pretentiousness, and hyper-sociality during my time there. This was especially true of those who pursued business, not to enforce stereotypes, but this is personal experience. Likewise, those who were heavy on scientific academia were narrow minded. They can memorize facts, but they didn't know how to be critically aware. In other words, they were used to the education institutions instructing them on 'what' to think, but they never learned 'how' to think for themselves. I'm familiar with a top high school student who got into my university with honors to pursue biology. He had to drop out of philosophy because he was failing it and it would affect his GPA. I know university students who have not read a book in their life. Personally, I don't see anything in drinking. Alcohol is overrated, and by judging the hype the student body gives it, especially with university clubs using pub crawls as a means to attract members, forget the merit of the actual club, people don't seem to really be questioning their values.

I feel you, OP. I was hoping to form some association of like minded students at my university, but good luck finding them.
