I've fought court battles over my inventions before.

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.

If you want to do something different, you’re going to come up against a lot of naysayers.

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

Success isn't a result of spontaneous combustion. You must set yourself on fire.

Make sure that you intentionally bring out results and positive products and the world will celebrate you.

Deception is mostly a game we play with ourselves.

I remember telling my classmates when I was 8-years-old that (being a sportscaster) is what I wanted to do. That was the only thing I ever wanted to do with my life.

I don't like throwing myself in a place that's going to rock my world.

Any action, in the fullness of time, sinks to nothingness.

And how to paint your lovely hands, fluttering over the silks like two dark birds?

The only way to understand something is to be confronted by something that is difficult to understand.

The wind in ones face makes one wise.

When the elephant decides to walk through the village, all the dogs come out and bark.
