Became a dad and realized I had to grow up for real

I was a total meathead before my son was born. Stayed out late, spent money on stupid stuff, didn't think about the future at all. Then suddenly I'm responsible for another human being and everything changes. I started reading parenting books, got my finances in order, actually think about my decisions now. I miss being able to be spontaneous and stupid sometimes but honestly becoming a parent is the best thing that ever happened to me. Made me an actual adult.
