Finance
by Nassim Nicholas Taleb
What gets stronger when shaken?
A wine glass breaks when you drop it. A rubber ball survives. Nassim Taleb asks about a third kind of thing, one that gains from shocks and disorder. There was no word for it, so he coined one, antifragile, and argues that modern life keeps smothering it.

Taleb borrows three myths. Damocles, with a sword hanging over him by a single hair, is fragile. The Phoenix, reborn from its ashes exactly as it was, merely survives. The Hydra grows two heads for every one cut off. That's antifragile, because the harm makes it stronger.
Iatrogenics means harm done by the healer, and Taleb sees it well beyond medicine. Doctors, central bankers and policymakers often step in where leaving things alone would work better, because doing something looks responsible. He calls this naive interventionism, and wants its side effects counted before anyone acts.
Put most of what you have somewhere very safe and a small part into bets with a big possible upside, and avoid the risky middle. Your worst case is small and known, and your best case is open. Taleb uses the same shape for careers as for money.
Taleb calls it via negativa. Removing something usually does more good than adding something. Quitting smoking or paying off a debt helps more than most things you could buy. Subtraction rarely has hidden side effects, while every new pill, rule or gadget brings some you didn't expect.
Antifragile
Some things get stronger from shocks. Taleb calls them antifragile, the opposite of fragile.
Stress
Muscles and bones grow stronger under strain. Shield something from every stress and it grows weak.
Meddling
Meddling to help often does harm. Doctors, officials and managers keep fixing things better left alone.
Barbell
Keep most of your money very safe and put a little into bold bets. Skip the middle.
Options
Cheap trial and error beats grand plans. Look for bets where a mistake costs little and a win pays a lot.
A story from the book
Taleb describes twin brothers. John works in a big bank's personnel department, on a steady salary. George drives a London taxi, and his takings change every day. John looks safer, until one round of layoffs leaves him with nothing. George's daily ups and downs keep him adaptable.
One thing to try
Instead of adding a new habit or tool this week, take one thing away. Cancel a subscription you never use, or drop a meeting that goes nowhere. Taleb's bet is that subtracting will help you more than any new plan.
