I've never sued anybody, though there have been one or two occasions I've wanted to strangle one or two people.

When I was young, every time I criticized someone, my mother would stand me in front of the mirror and say: 'The flaws you see in others are actually a reflection of yourself.' That taught me to pay close attention when I looked at others.

If something can't be explained on the back of an envelope, it's rubbish.

Two bricklayers work side by side. The first lays bricks. The second builds magnificent cathedrals. Think small vs. think big.

My very first venture was a national student magazine to try to campaign against the [Vietnam] War. And so I wanted to be an editor. I wanted to bring the magazine out. And in order for the magazine to survive I had to worry about the printing and the paper manufacturing and the distribution. And, you know, I had to try to, at the end of the year, have more money coming in than going out.

Remain focused on fulfilling your business mission. Never allow adversity divert your attention and efforts.

I never went into business just to make money - but I found that if I have fun, the money will come. I often ask myself, is my work fun and does it make me happy? I believe that the answer to that is more important than fame or fortune. If it stops being fun, I ask why? If I can't fix it, I stop doing it.
