Entrepreneurship: 10% coach, 20% player, 30% cheerleader, 40% waterboy.

I have a lot of faults. I often interrupt in meetings. I talk too loud. I talk too fast.

I believe there's plenty of market for each; we're talking about an ecosystem that is going to support billions of devices, so a competitive landscape is good for consumers, developers, and the platforms alike. Apple brings a smooth elegance to its devices and platform, with the best marketplace experience to boot. Google brings a higher volume of devices as well as a more diverse ecosystem to interact with. The real story here is that Microsoft is nowhere to be seen, ending a two-decade monopoly and creating biggest opportunity for software startups probably ever.

Opportunity lives at the intersection of what people need tomorrow and can be just barely built today.

My mom is proud of me. But she might not be too happy about the hours I keep or how little I eat. I wake up so late that it would be inappropriate to have breakfast. At most, I will have a snack in the day and dinner. I realize that it's not the healthiest way to live, but it's all I really have time for.

My workday begins around 11 A.M., with a cup of black coffee in each hand. If I had more hands, there would be more coffee.

I don't use many apps. I use naps.
