I would hope that a mature perspective would not make people think that their college of choice is always the best ever.

I think Gustavus was a good choice for me, but that doesn't mean it'd be a good choice for everybody, it doesn't mean there were no other possible good choices for me, and it certainly doesn't negate any of the glaring errors made in my time there. And anybody who can't name anything they'd like to improve about their school is not thinking critically enough about their own educational environment, in my opinion.
