Athletes at all ages are bigger and stronger than ever before. And they are being encouraged - sometimes even incentivized, as we recently learned was the case on at least one National Football League team - to play to injure.

The truth is, what Americans enjoy about football is much of what makes the sport dangerous. However, I believe there must be a way to find the art of success and vitality in football, without the driving the level of impact that causes serious risk of head trauma, paralysis and other life-changing injuries.

I understand human needs. I grew up where far too many people lived day to day without elemental needs like food and shelter.

My own philanthropic efforts have always included an educational element, whether it's expanding opportunities to educate a promising mind or extending the brain's ability to learn.

Teaching children about entrepreneurship is much like imparting any other skill or piece of knowledge. You will provide them with ways to experience how entrepreneurship works, and you guide them toward the subjects or areas they seem to show an interest in.

I have seen humility in many of the finest leaders I have met the world over. And indeed, it is embodied in the warm, engaging and quintessentially successful spirit of Sir Richard Branson.

If there is one thing I have learned on this incredible journey we call life, it is this: the sign of a truly successful individual is humility.
