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.

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.

As a father, I believe that involving children in sports at a young age is generally, a wise proposition.

As a young boy growing up in rural India, most of what I knew of the world was what I could see around me.
