Timing harnesses synchronicity, and it is an awe-inspiring and elusive art.
It is difficult to describe, but easy to recognize in action, where the supporting simultaneous events are usually interpreted as extraordinary strokes of luck.
Timing relies on the understanding that opportunities and trends clump together, not unlike matter behaves when attracted by a center of gravity, or electrons by a magnetic field.
One could describe timing as being in the right place at the right time, but it’s a lot more than that. Timing allows one to sense the direction and speed of events, sight unseen, in the absence of pertinent data.
It is to decision making as perfect pitch is to hearing: impossible to teach, but can be enhanced by discipline and sustained training.
