There is a glass ceiling for the Indian startups. If I want to meet the PM, it won't be as easy as a foreign guy coming to India. I understand that dynamic, and we need to make sure government sees us as major contributors to society, which is not full there.

Entrepreneurs are not driven by fear; they are driven by the idea to create impact.

I fully agree with innovation and letting the best product win.

Instead of letting the driver-base grow organically , we are setting up driver-training schools across different districts in the country.

I find my best writing time is actually 6 A.M., before the detritus of the day - the fish fingers and the school uniform and dogs and bills - have had a chance to clog up my brain. I can usually get 500 words done before 7 A.M. But it is difficult, and the Internet, and social networking, are terrible timesucks.

I think people should be able to have at their behest, like, four hours of music, entertainment, visual knowledge, different pathways. That's what I'm trying to do with modern technology, not just another song and another song.

At WhatsApp, our engineers spend all their time fixing bugs, adding new features and ironing out all the little intricacies in our task of bringing rich, affordable, reliable messaging to every phone in the world. That's our product, and that's our passion. Your data isn't even in the picture. We are simply not interested in any of it.

The reality is the technology exists now to extend life and have people live healthier, happier lives. Not to be kind of immortal - that's not what I'm talking about.
