CARL ICAHN

If you want a friend on Wall Street, get a dog.

In life and business, there are two cardinal sins. The first is to act precipitously without thought and the second is to not act at all.

I'm not Robin Hood. I don't take from the rich to give to the poor. I take from the rich.

Some people get rich studying artificial intelligence. Me, I make money studying natural stupidity.

The cardinal rule is to protect the downside.
