“Blessed is he who expects nothing, for he shall never be disappointed.”
My life experience has taught me to expect nothing. EVERY time you expect ANYTHING you are setting yourself up for disappointment. People just don't view themselves as obligated to you no matter what you might have done for them. That is not to say that everyone is an ingrate but it is to say that to expect from people is a sure recipe for disappointment, frustration and maybe even bitterness.
It is also worthwhile trying to determine what others expect from you so that you can be that special person who really sees their job in the world as making others happy.
It is rare.....
