If you want to be at the top of your game, you must close cycles. The principles apply to your career, your marriage and your life. Overwhelm is a consequence of having too many open cycles.
A cycle begins with an intention, is followed by action and is closed by the fulfillment of that intention. I intend to eat broccoli with dinner, for example, so I wash some broccoli, cook it, serve it and, finally, close the cycle by fulfilling my intention to eat broccoli.
The example, of course is cycle within a larger cycle of eating a meal, and that is within a yet larger cycle of maintaining health. We call a cycle “open” the moment the intention exists. It stays open until the intention is fulfilled. Obviously, each of us has many cycles open at any moment in time.
