Success is one of the worst enemies of success, because success tends to breed complacency and lack of humility.

How do we have a society that maximizes peace, civility and well-being for everyone? How do we have a system of individual rights in which people succeed by helping others improve their lives? We're a long way from that. So what, I mean, we got more to learn than we know, to me. So we need better ideas.

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 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.

How do we make people's lives better unless we find the truth of what works and what doesn't?

I've had the philosophy that John Adams expressed, in the kind of system that we're trying to create in this country: that this is a system for moral people. It will work for no other.
