It is much easier and safer to scare someone into submission than to beat them into submission.

No intelligent man has ever lost a fight to someone who said 'I'm gonna kick your ass'.

It's often been said, "Violence never solved anything." The simple truth is that when you are slammed up against the wall and the knife is at your throat, when a circle of teenagers is kicking you as you curl into a ball on the sidewalk, or when the man walks into your office building or school with a pair of guns and starts shooting, only violence, or the reasonable threat of violence, is going to save your life. In the extreme moment, only force can stop force.

Here's a rule of life: You don't get to pick what bad things happen to you

It's better to avoid than to run; better to run than to de-escalate; better to de-escalate than to fight; better to fight than to die. The very essence of self-defense is a thin list of things that might get you out alive when you are already screwed.

The only defense against evil, violent people is good people who are more skilled at violence.

Better to avoid than run, better to run than de-escalcate, better to de-escalate than fight, better to fight than die.
