I can't tell if I'm a particularly picky person or if my university was worse for cultivating the livelihood you describe, but it sounds just like the sort of thing I wish I'd gotten out of my college experience. In all likelihood, I just wasn't looking in the right places.
I was lucky enough, at least, to forge a few very solid friendships. But I have to admit that myself and my friends share very few passionate interests...at some point I gave up taking people at their word that they were interested in something! Not a good position.
The reason was, it felt like I kept meeting people who professed great love for some interest or another, but they had no interest in discussing it, ever! And often enough they devoted shockingly little time to it. (Maybe it's because of my interests? I was trying to hang out with artists.)
