About Happiness

I've heard the opinion that for being ok, or at least not depressed, it would just take to care less..
I don't feel I can agree with this, because if one would care always less, there would be no sense in anything left. And, as it seems, people are most satisfied from things they care about.
So I think what would help much more is to expect less, from life, from other people, from yourself.. Because when you don't expect things to happen, there is two things that will save you: Firstly, you will not be disappointed so often and, much more important, secondly, you will be much more capable to embrace and treasure good things once they actually happen.
