Went from selfish to actually caring about someone else
This might sound harsh but I was pretty self-centered before. My needs came first. Got married and that shifted a bit but I still had that core 'me first' mentality about a lot of things. Then my daughter was born and something just clicked. She needs me more than I need sleep, or free time, or buying stupid stuff I don't need. It's the weirdest transformation because I didn't do it on purpose, it just happened. I miss the freedom sometimes sure but I wouldn't go back for anything.
Navigating that shift right now as a first time dad and it's wild how quickly your priorities change. The selfish stuff just falls away.
