It is a sign of weakness to avoid showing signs of weakness.

When you beat up someone physically, you get excercise and stress relief; when you assault him verbally on the Internet, you just harm yourself.

An ad hominem attack against an individual, not against an idea, is highly flattering. It indicates that the person does not have anything intelligent to say about your message.

Bankers, they're not harmed by their mistakes. They benefit when things go right, and the society pays the price.

Few understand that procrastination is our natural defense, letting things take care of themselves and exercise their antifragility; it results from some ecological or naturalistic wisdom, and is not always bad - at an existential level, it is my body rebelling against its entrapment. It is my soul fighting the Procrustean bed of modernity.

Also, it's good to have more than one profession, in case your own profession goes out of style. A Wall Street trader who's also a belly dancer will do a lot better than a trader who winds up driving a taxi.

It has been more profitable for us to bind together in the wrong direction than to be alone in the right one.
