Tang Soo Do · Seven tenets
Concentration
Definition
Unwavering attention on the one rep, the one person, or the one task until it is finished.
The lesson
The tenet is not intensity. It is refusing to leave. In the hall that means the technique in front of you, not the rank you want or the mistake you just made. Outside it, the same theft happens: the phone, the next thing, the argument in your head.
Give one piece of training or work a single object of attention. When you leave, come back without a speech. The return is the tenet.
One undivided block. Count every time you return.
Busy switching that feels like effort and finishes nothing.
