If I wasn't a trader, I would probably be in the film business in some capacity and writing in some other form. I went to NYU Film School and London Film School.

On the very instant that we know that our assailant intends us serious physical harm, we must work just as fast as we can.

Let your attacker worry about his life. Don't hold back. Strike no more after he is incapable of further action, but see that he is stopped.

Don't try to be fancy. Shoot for the center of mass. The world is full of decent people. Criminals we can do without.

It is high time for society to stop worrying about the criminal, and to let the criminal start worrying about society. And by "society" I mean you.

The one who fights back retains his dignity and his self-respect.

Your physical safety is up to you, as it really always has been.
