From a very early age, I also realized I wanted to invent things. So I became really interested in technology and also then, soon after, in business, because I figured that inventing things wasn't any good; you really had to get them out into the world and have people use them to have any effect.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.

There are really two things that have to occur in order for a new technology to be affordable to the mass market. One is you need economies of scale. The other is you need to iterate on the design. You need to go through a few versions.

Design is not just what it looks like and feels like. Design is how it works.

It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

The only thing I understand deeply, because in my teens I was thinking about it, and every year of my life, is software. So I'll never be hands-on on anything except software.
