I was a kind of hyper-intense person in my twenties and very impatient.

Now, if you're rich, you can spend a lot of money, Netherlands-style, and reduce that. But Bangladesh or parts of India, like Calcutta, they just simply won't be able to afford that kind of protection.

The only role other than paying their taxes, whatever those are, the only role for philanthropy broadly - of which the rich should give disproportionately - the more, the better - and I think there is a positive trend in that direction - there are certain risk-taking things, like trying out a new type of charter school or funding a new kind of medicine.

I've always been interested in science - one of my favourite books is James Watson's 'Molecular Biology of the Gene.'

Fortunately for India, it has got a growing economy. If it is doing the right things with taxation and focusing on the right areas for human development, it is going to have no problem, over a period of time, taking care of its own needs.

When I was young I liked taking tests. I happened to be good at it. Certain subjects came easily, like math. All the science stuff. I would just read the textbooks in the first few days of class.

If the 1980s were about quality and the 1990s were about reengineering, then the 2000s will be about velocity.
