Use posture and body language to stay even-keel
To stay even-keel during a round, the speaker uses physical habits: keeping his eyes at horizon level rather than down on the ground, and walking with his chest a bit taller and good posture (he pictures how Adam Scott or Rory walks when playing well). He also puts his club back in the bag to walk to the next shot without standing there ruminating on the last one.
