I wanted to project myself forward to age 80 and say, 'OK, I'm looking back on my life. I want to minimise the number of regrets I have.' And I knew that when I was 80, I was not going to regret having tried this. I was not going to regret trying to participate in this thing called the Internet that I thought was going to be a really big deal.

I wanted to be able to build things. Actually, in college I built an inkjet printer out of Legos, because I wanted to be able to print really big images. I figured you could print really big posters really cheaply using inkjet cartridges. So I reverse-engineered the cartridge, and I built all the electronics and mechanics to drive it. Just sort of fun projects. I like to be able to do those kinds of things.

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.

Software is a great combination between artistry and engineering.

Software innovation, like almost every other kind of innovation, requires the ability to collaborate and share ideas with other people, and to sit down and talk with customers and get their feedback and understand their needs.

I was lucky to be involved and get to contribute to something that was important, which is empowering people with software.
