Yeah, I suppose you could say it is some Seinfeld-esque philosophy.

I work with a couple old cranky individuals that I've noticed would much rather complain about what they don't like than to enjoy what they do like. Everyone is going to gripe about what they don't like, including me, it's natural that we can't avoid all the unpleasantness of life. However, to only dwell on what makes us miserable and to fail to ever give any acknowledgement to what brings us pleasure is bizarre to me.
