Anger is a good motivator.

Life is a mountain of solvable problems and I enjoy that.

Cordless vacuums are designed for quick jobs, but you need enough power to do the job; you don't want the power waning over time.

Engineers are behind the cars we drive, the pills we pop and the way we power our homes.

As an engineer I'm constantly spotting problems and plotting how to solve them.

I made 5,127 prototypes of my vaccum before I got it right. There were 5,126 failures. But I learned from each one. That’s how I came up with a solution. So I don’t mind failure.

If you can't be unconventional, be obtuse. Be deliberately obtuse, because there are 5 billion people out there thinking in train tracks, and thinking what they have been taught to think.
