I believe the late Steven Covey made an observation that people sometimes view love as something you have or not; in other words, it’s a perspective that sees love as a noun.
But love, he pointed out, is also a verb. You can choose to love someone (or not). So if two people used to love each other but no longer do, did the love disappear because of a mysterious reason? Or did the two people just decide not to love each other anymore?
It seems like this lack of action might be limiting factor in other contexts. We don’t have to hope for the day that we’ll be more grateful, optimistic, or happy. We can simply make the decision, today.
