Humans aren't machines. In my experience it's very hard to actually have universally low expectations and be content with them in the long run. Usually people who say that either have low expectations in only certain areas (ie: material wealth, etc.) or are bottling up resentment (ie: the classic midlife crisis).

That's the point! It's very hard to have small expectations especially if you see your friends, colleagues or generally other people to 'be better' or 'have more', but if you can not care about this, you'll be happy. It is against human nature, though.
