How does one accomplish not having any expectations of people anymore?

I am constantly disappointed in people. And that's because I have high standards in human behavior.

But then, what's wrong with having high standards? Well, my high standards are constantly being brought down to low standards because people constantly disappoint me.

I think much of the human race is kind of just well, below par.

I don't think I should expect much of people anymore. Maybe that would help. I believe in honesty, kindness, honor, integrity, strong morals, and strong standards. I think this is in fact rare amongst the general human race.

Maybe I'm just jaded. I think I am.
