Design and technology should be the subject where mathematical brainboxes and science whizzkids turn their bright ideas into useful products.

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.

What I've learned from running is that the time to push hard is when you're hurting like crazy and you want to give up. Success is often just around the corner.

Enjoy failure and learn from it. You never learn from success.

Everyone gets knocked back, no one rises smoothly to the top without hindrance. The ones who succeed are those who say, right, let’s give it another go.

Successes teach you nothing. Failures teach you everything. Making mistakes is the most important thing you can do.

Everyone has ideas. They may be too busy or lack the confidence or technical ability to carry them out. But I want to carry them out. It is a matter of getting up and doing it.

In order to fix it, you need a passionate anger about something that doesn't work well.

Engineering undergraduates should not be charged fees. They should receive grants, not student loans, and the government will get the money back long-term from increased exports.

Children want the challenge of difficult tasks - just look how much better they are than their parents on a computer.

If you would have a boy to despise his mother, let her keep him at home, and spend her life in petting him up, and slaving to indulge his follies and caprices.

Believe nothing, not even yourself.

All right, let's not panic. I'll make the money by selling one of my livers. I can get by with one.

Average people look forward to "getting off." Successful people look forward to "getting on."

The person who really wants to do something finds a way; the other finds an excuse.

Working pretty much nonstop as an artist, the hardest thing is to know what to do with yourself when you have some time off. You struggle with yourself to take a vacation.

The days start to be charged not because tomorrow you're leaving, but because in three weeks you're leaving. The future impinges. So you start to think about the frame.

Don't think about things, just do them; don't predict them, just make them.

And like my dad always said, the first step is always the hardest.

Framing the issue of work-life balance - as if the two were dramatically opposed - practically ensures work will lose out. Who would ever choose work over life?
