Markus, I agree. I think that's true for two reasons - (1) even people who are generally happy need something 'bad' in their lives in order to have contrast with the good things; (2) Successful, happy people get that way because they're ambitious. If we didn't have something that we didn't like (ie, wanted to improve) we wouldn't have gotten as far as we have.

Happiness, to me, is striking a balance between what you have and what you desire - and then finding a way to get to what you desire.
