The work is easier when you have prepared for it. You will either be ready or not ready when the actual moment of a big meeting, a sales pitch, or a important presentation arrives. You’re work has been prepared, demonstrated/applied, and lived long before the actual moment. If you’ve prepared for and operated toward the purpose, you really just have to show up for that isolated moment in time to share what you have learned and set the stage for what is next.
If you are duly prepared coach for the isolated moments of an athletic contest, the probability of “winning” is considerably higher. Not much you can do about recruiting athletes, hiring a great staff, building a disciplined culture, and/or even game-planning right before the game. The preparation is what you should focus on and excel with, not the actual series of moments (games) as they arrive.
