Entrepreneurship is not really building a product, it's not having an idea, it's not being in the right place at the right time. It's fundamentally company building.

There is no greater country on Earth for entrepreneurship than America. In every category, from the high-tech world of Silicon Valley, where I live, to University R&D labs, to countless Main Street small business owners, Americans are taking risks, embracing new ideas and - most importantly - creating jobs.

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.

Every startup has a chance to change the world, by bringing not just a new product, but an entirely new institution into existence.

Lean thinking defines value as providing benefit to the customer; anything else is waste.

If the plan is to see what happens, a team is guaranteed to succeed - at seeing what happens - but won't necessarily gain validated learning - If you cannot fail, you cannot learn.

If you cannot fail, you cannot learn.
