I've asked Jobs why he didn't get an operation then and he said, 'I didn't want my body to be opened... I didn't want to be violated in that way.'

Without Steve Jobs, you would have well-designed computers, probably open and not integrated, but they wouldn't have sex appeal, they wouldn't have romance.

Was he smart? No, not exceptionally. Instead, he was a genius.

There are parts of his life and personality that are extremely messy, and that's the truth

Leonardo da Vinci had such a playful curiosity. If you read his notebooks, you'll see he's curious about what the tongue of a woodpecker looks like, but also why the sky is blue, or how an emotion forms on somebody's lips. He understood the beauty of everything. I've admired Leonardo my whole life, both as a kid who loved engineering - he was one of the coolest engineers in history - and then as a college student, when I travelled to see his notebooks and paintings.

Otherwise, as Dylan says, if you're not busy being born, you're busy dying.
