If you don't own Gold, you know neither history nor economics.

I have been very lucky because I have had the opportunity to see what it's like to have little or no money and what it's like to have a lot of it. I'm lucky because people make such a big deal of it and, if I didn't experience both, I wouldn't be able to know how important it really is for me. I can't comment on what having a lot of money means to others, but I do know that for me, having a lot more money isn't a lot better than having enough to cover the basics.

What I'm trying to say is that for the average investor, what I would encourage them to do is to understand there's inflation and growth - it can go higher and lower - and to have four different portfolios essentially that make up your total portfolio that gets you balanced.

Success is not in obtaining the thing. Because there's always another thing. And then you look back on it, and for me, through my evolution, yes I have success by most measures - but for me, when it comes to the greatest joy of reward, there's an emotional element and there's an intellectual element. Emotionally, my greatest joy was the personal relationships I've had. That was the greatest joy. Intellectually, my satisfaction was that I do feel I've evolved well and I'm doing my best to contribute toward evolution.

To have an idea meritocracy, one needs to do three things. First, they have to put their honest thoughts on the table, for everyone to look at and everyone to work through. Second, they need to have thoughtful disagreement, by which there are quality exchanges, in which there's open mindedness and the realization that no one has all the right answers. And you can work through that and get to better answers because good collective decision making is better than any individual decision making. And third, you have to have ways of getting past the disagreements if they remain.

I think it is in the nature of individuals and individual entities not to self-correct.

One of the greatest sources of problems in our society arises from people having loads of wrong theories in their heads - often theories that are critical of others - that they won't test by speaking to the relevant people about them. Instead, they talk behind people's backs, which leads to pervasive misinformation.
