have you ever considered volunteer work of some kind. Like helping people learn to read or serving the poor in a soup kitchen. Maybe you could get your sense of value from helping others. I’m not going to try to change you since you seem to have come to terms. But from the outside looking in, it’s bleak. I hate to see people living in that perspective.
I've definitely thought about volunteering but not to find a sense of value. I don't care about squeezing out bits of value in a mostly useless life. I don't want mine and would give it away for free if I could.
Anyway, for my father's day text, I'm going to send it in a few and say "Happy EARLY Father's Day." There's something less authentic about early and belated wishes. That's what I'm going for.
