There are billionaires and then there is William Henry “Bill” Gates III. Come to think of it, how many billionaires have “Bill” as their nickname? His parents sure knew what they were up to when they named him William. There is a good reason that Bill Gates is the richest man on earth today. The Creator figured there would have been no better heart or a more resolute mind to entrust such riches with. Gates brings the same steely aggression to philanthropy that helped him build Microsoft into an operating system powerhouse. Albert Einstein might have had Bill in mind when he said, “Intellectuals solve problems, geniuses prevent them.” Improving people’s health and giving them the chance to lift themselves out of extreme poverty and ensuring that all people have access to opportunities they need to succeed in school and life are the key goals of the Bill & Melinda Gates Foundation.

In this exclusive interaction with N Mahalakshmi and Rajesh Padmashali, he shares his thoughts on why he is doing what he is.
