My parents didn't believe in luck. They believed in hard work and in preparing me to take advantage of opportunity. Like many parents, they taught me to be generous but never to depend on the generosity of others.

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.

As a father, I believe that involving children in sports at a young age is generally, a wise proposition. I believe that healthy competition is... well... healthy; that sporting events foster a spirit of teamwork that far surpasses the events themselves; and that active participation keeps children moving and is good for their self-esteem.

I believe that entrepreneurs play an unmatched role and the accelerating pace of innovation is transforming the face of global challenges. You must think about the solution differently when you're trying to impact 1 billion people rather than affecting 1 million people.

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.

Success is not about how much money we have in the bank, but it's about how many peoples' lives we have impacted through it. Success is experienced when we do things which are never done before.

When I finally had the chance to make my childhood dream a reality - as a co-founder and chairman of Moon Express - my goal was to broaden participation in lunar exploration, and connect the common person to its results. We plan to send robotic rovers - not humans - to the Moon to search for precious metals and rare minerals on the Moon's surface.
