Over the long run, the price of gold approximates the total amount of money in circulation divided by the size of the gold stock. If the market price of gold moves a long way from this level, it may indicate a buying or selling opportunity.

The pain of problems is a call to find solutions rather than a reason for unhappiness and inaction, so it's silly, pointless, and harmful to be upset at the problems and choices that come at you (though it’s understandable).

Don't be a perfectionist, because perfectionists often spend too much time on little differences at the margins at the expense of other big, important things. Be an effective imperfectionist. Solutions that broadly work well (e.g., how people should contact each other in the event of crises) are generally better than highly specialized solutions (e.g., how each person should contact each other in the event of every conceivable crisis).

To be successful, we need everyone to think independently and work through disagreement to decide what's best.

The main reason I write the daily observations is because I want to know where I'm wrong. So lots of times if somebody points something out it helps me, and I want to have a diversified bet of uncorrelated bets.

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.

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.
