Interesting you should point this out. It really does matter what you do with your discontentment. There exists a whole race of people that aren't satisfied if they don't have anything to complain about. You've been around them before, complaining about everything, and everything is negative. They're impossible to be around, am I right? So they have a miserable attitude because they're sad and they're sad because they have a miserable attitude. It's a vicious cycle, but so long as you recognize such wacked-out behavior as it is; a cry for help.

The traditional (and indeed biological and natural) route is to cry for help because we are still close to our original nature as a species-being. But, I personally went through about four or five years or so of major depression as a young teenager (from about junior high to about my mid years of high school) and found my own rather introverted route of a mostly mental and 'spiritual' (if I may use the term for sakes of communication) though also physical development. The problem with the former path is that there really no longer exists such stable institutions to provide such an environment that meets our species-being in our bourgieois system. Likewise, people are upset when things do not match their expectations. I took my own initiative because I had to, but unfortunately not all can do that. Each person heals differently.

Sometimes it's more important to be at peace with your surroundings than attempt to create them to match your expectations.
