We can be all of these things as we grow into adulthood, but I experienced them so much differently as a father, watching my girls live them. ​ I'm not sure how thinking about this distinction will affect future me. I hope that it will help me to appreciate everyone in my life, especially my daughters and my wife, a bit more for who they are and who they have been. Maybe it will even help me be more generous to 2019 me.
