In Ignore Everybody, Hugh MacLeod talked about the Pissed off Gene that cause us to be dissatisfied no matter how well things are going. It's the urge that motivates us to create, improve and enhance our lives. He argues that we all have it in us. It's built-in since the caveman days.

The only people who can change the world are people who want to. And not everyone does.

Sadly, not everyone act on this urge and most will happily trade it for cash. If you are annoyed at how some things appear to be broken, use it as the drive to create something new. Apparently, it's okay to be pissed off sometimes.
