We have drastically different life experiences. In general I appreciate things a lot more in the moment than in retrospect. And I'm much happier now than I was as a child or a university student--the thing I appreciate most about those times is that they're over. And look, it's fine we have different experiences--I'm not here to invalidate your experience. But when people say stuff like "You cannot fully appreciate your moments without kids until you have kids though" you're invalidating my experiences. That's total bullshit--you don't know anything about my life and whether or not I truly appreciate it. If you want to talk about your experiences, that's cool, and I'm actually even interested to hear them. But don't pretend like your experience is some universal truth. It's not.
