Some of the best inventive moments are born out of 'wrong thinking'. Most people start with the right way so they all follow the same path. The wrong way will lead to mistakes from which you can learn and create new discoveries-the kind of original ideas that come to life when we dare to be different, keep an open mind, and have no fear of failure.

Arbitrary benchmarks cheat kids out of a fulfilling education.

If you really want to improve technology, if you want things to work better and be better, you've got to protect the person who spends a lot of effort, money, and time developing that new technology.

Failure is so much more interesting because you learn from it. That's what we should be teaching children at school, that being successful the first time, there's nothing in it. There's no interest, you learn nothing actually.

So I think the winners in recession are the people who produce new technology that does things better, which people really want.

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.

Nobody wants the expenditure of a lease on a factory which lasts 21 years. You can't plan 21 years ahead.
