"Fun fun fun till her daddy took the T-bird away". Life does take things away. The line in the Five Remembrances gets it: "All that is dear to me and everyone I love are of the nature to change." (The whole chant is at the bottom of this blog.) Fun is especially ephemeral. Every series has a finale, and sometimes it's a great disappointment.
The alternative is to invest yourself in the world. I thought I'd suggest one way to do that: Listen to someone else.
I don't mean listen the way therapists do, with intent to help you change. Don't do that. You don't know what someone else needs. And definitely don't listen the way most people do, thinking of the next thing they will say, even downright impatient. Just pay attention to that other person.
You can briefly take in yourself at the same time. Your self might be cringing before someone else's misery or bored with their same old story. Maybe at some later time you should examine that cringing or boredom that is taking the space where there could be compassion. Meanwhile, why not let them talk - they must have a reason for repeating that story - and just really listen, look. You can nod. You don't have to say anything. Or fix them. In fact, they'd probably pay you not to.
Listening to other people is actually a good way to chip away at our devotion to Wun, my term for our own constructed selves, that Wun who seeks everywhere for happiness when, in fact, the moment is right here.
