Probably the magic moment in my marriage. The realization that I need to accept far more than I need to expect. A person is who s/he is. Unless the person sees a need to change, s/he wont. So, my expectations remain unfulfilled as she does not see the need to change. Unhappiness increases. So, I decrease expectations and increase acceptance. Now, I am more peaceful and happier.
Expectation goes down -> Acceptance goes up -> Happiness goes up.
And now I try to explain the same to my wife - expect less from me to increase your happiness. So far, not much success...
