One Sport you have to zone in is, Rockclimbing on serious stuff. But you dont go on a serious Climb without experiance, or you get hurt even Killed same as Boxing. Ive seen Boxers in the Dressing Room zoned in, by the time they have reached the Ring there Bottles completely gone. Thats when reality clicks in or occasion Hits Home. Doubts set in about preperation affecting confidence, everybody is different.
