I want entrepreneurs to be engineers and scientists and designers; they don't necessarily have to be Internet entrepreneurs or retail entrepreneurs.

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.

Poetry is a mirror which makes beautiful that which is distorted

Mr. President, it is time for you to give me back my country. You can either continue to make fools of the people who elected a tyrant like you or let the country rise phoenix-like from the ashes.

Bravery and faith bring both material and spiritual rewards.

When an image is said to be singular, it is meant that it is absolutely determinate in all respects. Every possible character, or the negative thereof, must be true of such an image.

I actually do think the history is so epic that it actually kind of writes itself.

It is increasingly clear that the fate of the universe will come to depend more and more on individuals as the bungling of bureaucracy permeates every corner of our existence.

To me, lighting really sets the mood for a room. A 40 watt bulb in a cheap lamp is the same as a 40 watt bulb in an expensive one.

It is difficult at times to repress the thought that history is about as instructive as an abattoir.

Wisdom belongs in wonder.

Playwriting gets into your blood and you can't stop it. At least not until the producers or the public tell you to.
