I'll just add a quick comment here to build on what LG has already started. Another way I choose to assist my sub in honing her patience would be to have her go sit and meditate until I say otherwise. Here the length of meditation time is unknown, so it requires her to just relax and allow me to control her. The meditation ends when I say it does, a fact that allows her to learn patience, and obedience. She has to surrender her own will to me, and relinquish control. It can be very effective, as long as it's taken seriously by the sub.
