Throughout my career in martial art training, I would say that the majority of people I’ve met–my fellow students, my peers or acquaintances,  are people who are happy to train with what they think is an exemplary teacher. For a number of reasons, however, (lack of drive, humility, reticence to push themselves forward .. .  . .), they act as if they have an endless amount of time to learn the system.

That’s not so. Your teachers age, and as they do so, invariably, they cannot move as they once did. Some not only lose skill, but they lose knowledge. Others lose wisdom itself. Still others change: what seemed so important once is irrelevant to them as they approach, ever closer, to death, and their students’ mastery of their particular combative art no longer seems that important. In other words, their fire has burned out.
