Another aspect of the excellent Combat Instructor is focus. Focus is an interesting word, but in our context it refers to a startling clarity of understanding, and a intense attention to mission. It is not simply "being in the moment" as we so often hear from the Zen crowd...it is Owning that moment.
There are degrees of focus of course and 100% focus cannot be maintained indefinitely. And you will find that when at that level of focus, or perhaps an equally useful word - intensity - others become intimidated and uncomfortable. When the instructor is demonstrating an action or a tactic, he must turn on that 100% focus on demand. When he is running a class, he must maintain his focus so that he controls the direction and tempo of the class. A lazy instructor will lead to a boring class.
Controlling the direction and tempo involves having a schedule of events...an order of things so to speak. Somethings must be taught before others, and if we are to arrive at a complete and cohesive conclusion at the end of the class, they must be kept on schedule. We don't need to be excessively obsessive about it, but it does demand "focus". If you are focused, your class will be focused. If you are both focused, you will accomplish your mission.
Things that detract from focus maintenance for an instructor:
1). Allowing distracting thoughts to intrude while performing.
2). Allowing negative thinking (ie., I might miss this shot).
3). Not being eloquent in speech and running on with overly complex explanations (see thread on eloquence).
4). Allowing students to lead the tempo (you must have some consideration for this, but do not sacrifice the mission for one)
5). Allowing excess discussions and bunny trails to derail the time table.
In short, have a plan, devote all mental energies to that plan, and with few deviations, stay to the time table of the plan.
Funny, how while the discussion is for presenting a course of instruction, this applies to a great many things in life...like gunfighting.
