The theory of randomness is fundamentally a codification of common sense. - Leonard Mlodinow

Obviously it can be a mistake to assign brilliance in proportion to wealth. We cannot see a persons potential, only his or her results, so we often misjudge people by thinking that the results must reflect the person. The normal accident theory of life shows not that the connection between actions and rewards is random but that random influences are as important as our qualities and actions.

It is one of those contradictions of life that although measurement always carries uncertainty, the uncertainty in measurement is rarely discussed.

What I have learned, above all, is to keep marching forward because the best news is that since chance does play a role, one important factor in success is under our control: the number of at bats, the number of chances taken, the number of opportunities seized.
