6. Do no hurry your actions (Depending on the situation, do not haste your actions and make sure that each move is precisely and mindfully done and with a calm mind.)
 

7. Do not disturb the flow of the rhythm of the movements.
 

8. Do not fear.  (When you feel fear, your action will not be done with confidence.)
