Better to have bad news that's true than good news we made up

Leadership requires creating conditions that enable employees to do the kinds of experimentation that entrepreneurship requires.

A head start is rarely large enough to matter, and time spent in stealth mode-away from customers-is unlikely to provide a head start. The only way to win is to learn faster than anyone else.

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.

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.

Our educational system is not preparing people for the 21st Century. Failure is an essential part of entrepreneurship. If you work hard, you can get an 'A' pretty much guaranteed, but in entrepreneurship, that's not how it works.

In a startup, both the problem and solution are unknown.
