Jennifer and my children are testing for their Black Belts in Tae Kwon Do (TKD) this weekend. It’s kind of a big deal. This test, six and a half hours in total, is the culmination of four years of study. They have each hit their own personal Black Belt walls and wanted to quit. As I wrote about in Quitters, Campers, and Quitters: Which One Are You?, what matters is that they didn’t quit and, as their parents, we didn’t quit on them.
