Don't aim to be perfect! Aim to be antifragile

My point taken further is that True and False (hence what we call "belief") play a poor, secondary role in human decisions; it is the payoff from the True and the False that dominates-and it is almost always asymmetric, with one consequence much bigger than the other, i.e., harboring positive and negative asymmetries (fragile or antifragile). Let me explain.

You find peace by coming to terms with what you don't know.

Deficits are like putting dynamite in the hands of children. They can get out of control very quickly.

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.

Comfort makes you weaker. We need some variability, some stressors. Not too much, but just enough.

If you sat with a pencil and jotted down all the decisions you've taken in the past week, or, if you could, over your lifetime, you would realize that almost all of them have had asymmetric payoff, with one side carrying a larger consequence than the other. You decide principally based on fragility, not probability. Or to rephrase, You decide principally based on fragility, not so much on True/False.
