“I don’t have a lot of regrets in life, but one of my biggest is that when my son Kyle was about 10 and was proudly demonstrating how many laps he could swim underwater without taking a breath, I jumped in the pool and swam one more length than he did. It was an unthinking moment, and a great demonstration of the destructive power of competitiveness. I didn’t just show up my child; I risked damaging his self-confidence and our bond.”
