The most frequently asked question I hear first-time entrepreneurs ask is, 'How do I know when to launch my product?' The answer, more often than not, should be: 'Now!'

It's a simple fact: no individual can be good at everything. Everyone needs people around them who have complimentary sets of skills.

As a young boy growing up in rural India, most of what I knew of the world was what I could see around me. But each night, I would look at the Moon - it was impossibly far away, yet it held a special attraction because it allowed me to dream beyond my village and country, and think about the rest of the world and space.

Think so big, so audacious that people will think you are crazy.

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.

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.

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.
