Colonialism has a bad reputation in the modern context, but Colonial Africa was a far better place for both black and white before the colonists gave up.

The criminal does not expect his prey to fight back. May he never choose you, but, if he does, surprise him.

When under attack, it is necessary to evaluate the situation and to decide instantly upon a proper course of action, to be carried out immediately with all the force you can bring to bear. He who hesitates is indeed lost. Do not soliloquize. Do not delay. Be decisive.

Use your eyes. Do not enter unfamiliar areas that you cannot observe first. Make it a practice to swing wide around corners, use window glass for rearward visibility, and get something solid behind you when you pause.

It is true that a victim who fights back may suffer for it, but one who does not almost certainly will suffer for it.

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

By doing what our assailant least expects us to do, we may throw him completely off. ... what he usually least suspects is instant, violent counterattack, so the principle of aggressiveness is closely tied to threat of surprise.
