I'm not the same person and that's actually okay

Got some perspective this week. I realized I'm not the guy who stayed out till 2 AM anymore and that used to bother me. But then I watched my daughter learn to smile and I'm like... okay yeah I'd trade a thousand late nights for this. I'm softer now. More patient. Still me but like a better version I guess. Anyone else have that moment where you stopped grieving who you were and started being grateful for who you're becoming?
