You'll remember Newton was furious at Leibniz, because he developed calculus at the same time. And he went to his death believing that he had copied him. And no, it's because all the elements were there, so it's almost inevitable that the next discovery - as long as people are free and allowed to experiment and try new things.

You can't start taking away benefits if people don't have any opportunities.

My view on well-being and fulfillment comes from Maslow and positive psychology, and that is that you're satisfying three sets of needs. First need is physiological and safety needs: Got to satisfy those first. And the second is you got to satisfy your community needs because we're social animals, and if we don't have that, we're empty and we don't have people to share knowledge and bounce things off of, and challenge ourselves. And then the third is the idea is to find a calling.

I didn't think I was good at anything, didn't do well in school. And then in the third grade, I was going to a public school. And the teacher was putting math problems on the board. And I said to myself - it's amazing how you can remember certain incidents at any age that made an impression - I asked myself why is she putting those up when the answers are obvious. And then I saw it wasn't obvious to anybody else in the class. So I said, "Hey, I'm good at something."

If you're a leader at any level and your people aren't challenging you, you've got to change that or you can't be a leader here because you're not going to be using ideas, you're not going to have innovation, you're not going to fully develop your people. And if you're working in a group and you don't challenge, then you're not really doing your job.

My father would always say "learn everything you can and whenever you can, because you never know when it'll come in handy."

Best part of my job is fulfillment. When I see that, that we're creating value, that we're helping improve people's lives, and we benefit from it, so it's a system of mutual benefit. Our philosophy's working. That's what turns me on. That's what keeps me going.
