You know how people always talk about how vision is the key to entrepreneurship and perseverance and really seeing what other people don't see? We can actually redeem a fair amount of that folk wisdom.

Science and vision are not opposites or even at odds. They need each other. I sometimes hear other startup folks say something along the lines of: 'If entrepreneurship was a science, then anyone could do it.' I'd like to point out that even science is a science, and still very few people can do it, let alone do it well.

The United States is locked in a new arms race for that most precious resource - the future entrepreneurs upon whom economic growth depends. Substantial research shows that immigrants play a key role in American job creation.

If you don't know who your customer is, you don't know what quality is.

I believe for the first time in history, entrepreneurship is now a viable career.

The big question of our time is not Can it be built? but Should it be built? This places us in an unusual historical moment: our future prosperity depends on the quality of our collective imaginations.

The goal of every startup experiment is to discover how to build a sustainable business around that vision.
