The hour begins five minutes before the client arrives
A lesson rarely fails because the coach did not know what to teach. It fails, when it fails, because the coach walked into the hour still thinking about the previous one. The five minutes before the lesson are the most undervalued piece of preparation in a private practice.
Most coaches have a version of this experience. The morning has been busy, the previous client overran by ten minutes, the next one is already on court, and the first fifteen minutes of the lesson are spent catching up to a session that is already moving. The hour ends fine, but it is a fine hour, not a good one. The small ritual that prevents this is shorter than it sounds and changes the texture of the week.
Preparation, for a private coach, is not the same as planning. Planning is what was done after the previous lesson or when the block was first sketched out. Preparation is the act of arriving in the room ready to teach this client, today, in the state they are actually in. The two are different jobs and they need to be done at different times.
