“Reality is far more vicious than Russian roulette. First, it delivers the fatal bullet rather infrequently, like a revolver that would have hundreds, even thousands of chambers instead of six. After a few dozen tries, one forgets about the existence of a bullet, under a numbing false sense of security. Second, unlike a well-defined precise game like Russian roulette, where the risks are visible to anyone capable of multiplying and dividing by six, one does not observe the barrel of reality. One is capable of unwittingly playing Russian roulette - and calling it by some alternative “low risk” game.”

“Suppose a country starts its independence with the three economic characteristics that globally make a country prone to civil war: low income, slow growth, and dependence upon primary commodity exports. It is playing Russian roulette. That is not just an idle metaphor: the risk that a country in the bottom billion falls into civil war in any five-year period is nearly one in six, the same risk facing a player of Russian roulette.”

“With most people suicide is like Russian roulette. Only one chamber has a bullet. With the Lisbon girls, the gun was loaded. A bullet for family abuse. A bullet for genetic predisposition. A bullet for historical malaise. A bullet for inevitable momentum. The two other bullets are impossible to name, but that doesn't mean the chambers were empty.”

“The real first kiss is the one that tells you what it feels like to be an adult and doesn't let you be a child anymore. The first kiss is the one that you suffer the consequences of. It was as if I had been playing Russian roulette and finally got the cylinder with the bullet in it.”

“If you have more than one reason to do something (choose a doctor or veterinarian, hire a gardener or an employee, marry a person, go on a trip), just don’t do it. It does not mean that one reason is better than two, just that by invoking more than one reason you are trying to convince yourself to do something. Obvious decisions (robust to error) require no more than a single reason.”

“Many people keep deploring the low level of formal education in the United states (as defined by, say, math grades). Yet these fail to realize that the new comes from here and gets imitated elsewhere. And it is not thanks to universities, which obviously claim a lot more credit than their accomplishments warrant. Like Britain in the Industrial Revolution, America's asset is, simply, risk taking and the use of optionality, this remarkable ability to engage in rational forms fo trial and error, with no comparative shame in failing again, starting again, and repeating failure.”

“As a matter of fact, your happiness depends far more on the number of instances of positive feelings, what psychologists call "positive effect", then on their intensity when they hit. In other words, good news is good news first. How good matters rather little. So to have a pleasant life you should spread those small effects across time as evenly as possible. Plenty of mildly good news is preferable to one single lump of great news. The same is property in reverse applies to our unhappiness. It is better to lump all your pain into a brief period, rather than have it spread out over a long time.”
