You never win an argument until they attack your person.

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.

Another definition of modernity: conversations can be more and more completely reconstructed with clips from other conversations taking place at the same time on the planet.

Never take advice from anyone in a tie. They'll bankrupt you. Don't ask a general for advice on war, and don't ask a broker for advice on money.

Go to parties. You can't even start to know what you may find on the envelope of serendipity. If you suffer from agoraphobia, send colleagues.

Let me be more aggressive: we are largely better at doing than we are at thinking, thanks to antifragility. I’d rather be dumb and antifragile than extremely smart and fragile, any time.

...maximize the serendipity around you.
