My greatest challenge has been to change the mindset of people. Mindsets play strange tricks on us. We see things the way our minds have instructed our eyes to see.
There is the expression of selfishness and there is the expression of selflessness - but economists or theoreticians never touched that part. They said: 'Go and become a philanthropist.' I said, 'No, I can do that in the business world, create a different kind of business - a business based on selflessness.'
