A patent, or invention, is any assemblage of technologies or ideas that you can put together that nobody put together that way before. That's how the patent office defines it. That's an invention

Most of the time you will fail, but you will also occasionally succeed. Those occasional successes make all the hard work and sacrifice worthwhile.

Whatever the marketplace, if talented people are given resources, they're going to keep driving us to having better, simpler, cheaper solutions to problems.

The word entrepreneur is associated with success and adventure. From my life, the only thing I can tell you that's consistently associated with entrepreneurship is failure, and the only thing consistently associated with invention is frustration. There is a long road between the idea and the reality.

What really makes it an invention is that someone decides not to change the solution to a known problem, but to change the question.

My biggest worry is I'm running out of time and energy. Thirty years ago I thought 10 years was a really long time.

If you're going to fail, you might as well fail at the big ones.
