Stay focused on the mission.

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.

Being a father has been, without a doubt, my greatest source of achievement, pride and inspiration. Fatherhood has taught me about unconditional love, reinforced the importance of giving back and taught me how to be a better person.

All the conservation efforts in the world won't be enough to make a dent in the oncoming sustainability crisis our planet faces.

Success is not how much money you have in a bank. Success is how many lives you have touched.

I believe we need a more opportunistic and democratic approach to lunar exploration, now that we're shifting from U.S. government-sponsored space exploration to private expeditions.

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.
