For golfers the key element about this quote from The Godfather of Flow (Zone) is the Ego.
Aside from the quality of your golf swing... the biggest cause of bad golf shots is your inability to separate yourself from your ego.
Pressure, anxiety, doubt and fear all come from the ego and the inability to be in the present moment.
Accessing Presence is one of core elements of my Zone Action Plans for golfers.
More Presence equals less bad shots and lower scores... Fast!
