Some would say to not have any expectations at all. But I wouldn’t go that far. I think healthy, realistic expectations that are communicated are good to have. They’re something to reach for.
But when you come into a situation and your expectations aren’t met, let your observation take the lead. Discard your expectation in the moment and deal with reality at hand or you’ll find yourself in the middle of that silent marriage killer.
Tired of being frustrated? Then set aside your unmet expectations and face reality head-on. Then, after the fact, have a conversation with whoever is involved about what you expect and why.
