Philanthropy without scale and sustainability is like any other bad business that will simply wither and die on the vine.

I've been an entrepreneur all my life, and my recent focus is on finding entrepreneurial solutions to address global challenges in healthcare and education.

Great entrepreneurs focus intensely on an opportunity where others see nothing. This focus and intensity helps to eliminate wasted effort and distractions. Most companies die from indigestion rather than starvation, i.e. companies suffer from doing too many things at the same time rather than doing too few things very well.

Apple Computer would not have reached its current peak of success if it had feared to roll the dice and launch products that didn't always hit the mark. In the mid-1990s, the company was considered washed up. Steve Jobs had departed, and a string of lackluster product launches unrelated to the company's core business had failed to catch fire.

What separates sports from entrepreneurism, however, is that in business we constantly have to overcome undefined and unpredictable challenges. Athletes train for specific events and conditions, whereas entrepreneurs generally have little idea what they will encounter along the way.

I believe our legacy will be defined by the accomplishments and fearless nature by which our daughters and sons take on the global challenges we face. I also wonder if perhaps the most lasting expression of one's humility lies in our ability to foster and mentor our children.

We are now living in a fast paced technological era where every skill that we teach our children becomes obsolete in the 10 to 15 years due to exponentially growing technological advances.
