The great Col. Jeff Cooper for all practical purposes founded the modern defensive firearms training community. He was intimately involved in teaching people how to shoot for most of his 86 years. As such, he had many insights into what went into the making of a good instructor. While he was speaking to the ability to teach shooting, his guidelines have as much direct connection to the instruction of H2H fighting as well. Here is an excerpt from some of his writings:

“….a good instructor, above all, must seek his student’s excellence. He must place more value on his ability to teach a man to shoot than on his own ability to shoot. His work gratifies his ego when his student becomes a good shot, and improvement is more satisfying to the ego than excellence. It is fine to raise a B shooter to the A category, but it is far better to raise a D to a B……… (a good instructor) must realize that matters which are quite obvious to him may be complete mysteries to a novice. This sort of knowledge is not inherent and must be acquired through experience.”

So much good stuff there.
