I would disagree with point 8. I tend to go for superficial friendships over close ones (by choice), and it works out to be a better deal. One thing is that you get a lot more diverse set of friends when you are not going that deep. Secondly, deep friendships kind of lock you in, and I do not like that. Thirdly, having a large set of friends, exposes you to more interesting opportunities and new friends that having a few close friends doesn't. Moreover, a lot of pathologies like jealousies etc don't show up with casual friends. They often come up in ugly ways with close ones.
