I was the party guy and now I'm the guy with the diaper bag
This is random but I was looking through old pics last night. Pre-kids me was always out, always organizing trips, always the center of attention at parties. Had a different girl every few months. Now I'm married with two kids, I own a minivan (shocking myself daily), and the most exciting thing in my week is getting both kids to bed by 8 PM so I can watch one episode of a show with my wife before passing out. I genuinely do not recognize that old guy. What's wild is I'm actually happier now. I thought I'd hate this life but having purpose beyond myself changed everything.
Sounds like you're navigating that transition. Fatherhood rewires what matters, but that party guy is still in there somewhere between the diapers and the responsibility.
