Close your eyes and think back to a moment in your life when you felt the sensation of absolute certainty. Of being confidently and optimistically at home in your bones. A deep sense of belonging right where you were, doing exactly what you were supposed to be doing. Visualize the place. What kind of day was it? Try recalling the events that led up to the experience. Were you alone? If not, who was with you? Try re-experiencing the letting-go-ness of it, like dropping in an elevator. That instance of invincibility. Freedom from the furrowing forehead, from jaws judgmentally clenched in defense. Shoulders surrendered, slackened, and relaxed - perhaps a sky-wide sigh of satisfaction so deep it was intoxicating. Like the warmth of saturating sunlight after a long damp night, wind blowing down your neck. A feeling of being loose and ready for anything. The uncanniness of deep belonging. A rightness in the gut so authentic that you know you are home. What was it like? Was there a settling, like all the puzzle pieces falling into place? A sense of elation? Perhaps waves of warm electricity running through your body and skull that felt so powerfully primordial, that, while unfamiliar, could only originate in the physics of something instantaneous, important, and real.Whether you lead others or just yourself, you have the right to a certain life. The Certainty Principle (TCP) is about deciding and acting to manifest that right. You will discover a powerful formula for certainty so fundamental that it will quickly feel familiar. But "knowing" it is not "living" it. TCP challenges the reader to transform themselves from "knowing" the path to "walking" the path of absolute and complete certainty. A simple choice once you understand there really is no choice because - as you will learn - "your horizon is forever."
