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.

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.

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.

Governments take too long to get things done and there are far too many varied interests at stake. If you were starting a business today and needed a partner, you would never choose a large bureaucratic institution like the government.

'Being green' is commendable, but I hope that people don't take too much pride and self-adoration because they shut off the water when they brushed their teeth. The truth of the matter is, conservation alone will do little to save our planet.

Sometimes a faint voice based on instinct resonates far more strongly than overpowering logic.
