I had long since forgotten the idea of setting mission and vision statements for raising kids, but being the person I am, I ended up thinking through "parent goals" anyway. One goal I settled on was to help my kids be as independent as possible as early as possible.
The other morning, my son said "I will wait for [friend] at school. I don't need you." It was momentarily sad, but I remembered my parent goal and remembered to feel proud about it.
