Playing the odds is an extraordinarily effective way to operate, and it pervades everything they do, including how they manage their time, how they construct a calm environment in which to think, whom they hang out with and steer clear of, how they guard against biases and blind spots, how they learn from mistakes and avoid repeating them, how they handle stress and adversity, how they think about honesty and integrity, how they spend money and give it away, and how they attempt to build lives imbued with a meaning that transcends money.
