The self-edited author is as foolish as the self-medicated patient.

When you’ve worked hard and done well and walked through that doorway of opportunity, you do not slam it shut behind you.

Customers can tell you how to evolve a product, but they can't show you how to make a leap.

"Patents make our product defensible." The optimal number of times to use the P word in a presentation is one. Just once, say, "We have filed patents for what we are doing." Done. The second time you say it, venture capitalists begin to suspect that you are depending too much on patents for defensibility. The third time you say it, you are holding a sign above your head that says, "I am clueless."

The desire to change the world is a tremendous advantage as you travel down the difficult path ahead because focusing on a lofty goal is more energizing and attracts more talent than simply making a buck.

Entrepreneurship is not for everyone.

A 50-year-old company can innovate as well as two guys/gals in a garage.
