I don't know anyone who actually likes the dark or night-time. I don't care how much they say it doesn't bother them. That's why we used to huddle in caves and light fires when the sun went down.
My guiding principle is that prosperity can be shared. We can create wealth together. The global economy is not a zero-sum game.
I was a little late in the game for Twitter and Facebook and everything because I thought, 'Oh, I don't know. I just don't have time.'
