It came into focus for me, over the break, that my mindset has a habit of embracing resentment. in lieu of embracing enjoyment. I'd rather resent that someone broke the "no gift" rule than enjoy the generosity they offered me. I'd rather resent the time demanded of me than enjoy the moment of the companionship.
Granted, in some of those cases it would take me considerable effort to find the enjoyment. (For example in the situation where one is not particularly fond of one's companion.) For the most part, however, there is some low hanging enjoyment that I am capable of grasping.
While I continue last year's jouney of letting go, I will add to the list the idea of letting go of resentment to make room for accepting enjoyment.
