Few understand that procrastination is our natural defense, letting things take care of themselves and exercise their antifragility; it results from some ecological or naturalistic wisdom, and is not always bad - at an existential level, it is my body rebelling against its entrapment. It is my soul fighting the Procrustean bed of modernity.

Financial institutions have been merging into a smaller number of very large banks. Almost all banks are interrelated. So the financial ecology is swelling into gigantic, incestuous, bureaucratic banks-when one fails, they all fall. We have moved from a diversified ecology of small banks, with varied lending policies, to a more homogeneous framework of firms that all resemble one another. True, we now have fewer failures, but when they occur... I shiver at the thought.

The narrative fallacy addresses our limited ability to look at sequences of facts without weaving an explanation into them, or, equivalently, forcing a logical link, an arrow of relationship, upon them. Explanations bind facts together. They make them all the more easily remembered; they help them make more sense. Where this propensity can go wrong is when it increases our impression of understanding.

I'm a private intellectual, not a public one.

Never take advice from anyone in a tie. They'll bankrupt you. Don't ask a general for advice on war, and don't ask a broker for advice on money.

I don't know anyone on Wall Street who goes to work every day thinking of anything but how to increase their bonus.

Never trust a journalist unless she's your mother.
