Growing up in a group home, and with an undiagnosed learning disability to boot, the odds of success were not on my side. But when I joined the high school football team, I learned the value of discipline, focus, persistence, and teamwork - all skills that have proven vital to my career as a C.E.O. and social entrepreneur.

Our education system is increasingly embracing a black-and-white way of thinking, in which 'learning' and 'play' are diametrically opposed. 'Learning' is the serious stuff that happens inside a classroom and can be measured via multiple choice questions and a No. 2 pencil. 'Play' is frivolous, fun, and worst of all, optional.

Sendak's 1963 classic 'Where The Wild Things Are' has long been a favorite of mine because of the creative imagery, fantastic adventures and, most of all, because of how this timeless story shows us that children need to be free to roam, explore and invent in order to understand their place in the world that surrounds them.

The lack of free, child-directed play time for our kids today will have dire consequences for these future leaders, making them less prepared to solve complex challenges and problems.
