9) Bottom up is better than top down. Bottom up is the fight for success of little small parts, easily fixed and changed. Top Down is good as long as it is always right. However the errors are huge and institution threatening. Taleb actually makes the case that freedom is more important than peace.

10) React to signal not noise. Only look at very large changes in conditions not small ones. Otherwise you can get problems from intervening, causing unintended consequences. Information has a nasty property of hiding failures because of the great opportunities to cherry pick results. Detail gives us comfort when it should not. We react to change more than direction.

11) Have a surplus of options. Get out of debt. It would be better to live in a smaller house with no debt than a fancy house with a huge debt. Have multiple career options and a backup plan. Need and want less, then you are not susceptible. Avoid stupid risks like smoking. Use emotions to make one successful by transforming fear into prudence, pain into information, mistakes into initiation and desire into undertaking.

12) Avoid banking on the mean or the middle, instead build a bimodal strategy that builds for maximally safe and maximally speculative. For example, in every economy the super rich have money to waste. Better yet instead of doing a single path analysis, do multiple path assessments. Taleb gives some great examples where one can win big with a 20% chance of winning as long as the winning is huge and one invests in multiple 20% big win chances. Asymmetrical relationships are key here. A 10% increase in New York Traffic does not cause a 10% slowdown, it causes total blockage. Track payoffs not probabilities.
