My technique was suggested by my older cousins.
They told me if I punched the first bully that laid a hand on me in the face I'd be left alone.
That worked great in elementary. I only needed to punch Jimmy Hoffa once in second grade. Real name of a real kid, not the mobster, of course.
In secondary it took a little more work but overall it worked there too.
By high school it was clear sailing.
