I've just got an exceptional memory, if I say so myself.

I get angry when people bring derisory actions against me.

An entrepreneur is not what you call yourself, it's what someone calls you in recognition of what you've achieved. I call Richard Branson an entrepreneur. Rupert Murdoch called me one. Anybody who stands up and says: 'I'm an entrepreneur' needs shooting. You'll drive people crazy.

A good leader is not necessarily the most popular person in their business, but the best ones are liked because they are respected for their clarity and vision.

If you enjoy what you do, don't be afraid of expressing your enthusiasm. Enjoyment is infectious.

If there was a market in mass-produced portable nuclear weapons, we'd market them, too.

I'm a commercial person, not an academic.
