One simple but effective technique is to practice the above three stages by focusing at a point where the eyebrows meet the bridge of the nose. Do this completely relaxed with eyes closed and adjusting the focal point slightly forwards/backwards until you feel a sudden relaxation/jolt (slight but distinct) within the body. Its like a physiological trick but once experienced you will know it and can then use it to calm down and concentrate whenever and wherever as needed.
