Leave It On The Field
Leaving it all on the field first involves a person’s relationships to him or herself and to his or her field. Almost always when this imperative is called out, it requires the person to recall focus, energy and skill that they have spent years working to perfect. Its importance began early with the individual's time and effort to master and practice their expertise. It plays out early and durably during practice that refines the perceptual and attention tools, builds up the body memory and the physical and emotional endurance. Without this training, preparation, pattern recognition and experience, most individuals will not be able to adjust their energy level and maintain or draw upon resilience under immense stress.
If a person or player had not devoted the time to acquire this mastery, there would be little to call upon to leave on the field.
