The Intense Preparation Olympian Kerri Walsh Jennings Is Undertaking Before Rio

"Before I had my kids I was like, 'this feels trivial,' because I’ve been playing for so long. All of my eggs are in one basket and it’s all very self-centered. Self-focused. They gave me that perspective and that balance I was missing. And then it took my game, my desire, my passion for the game to the next, next, next level. I’m hugely indebted to my children."
