A good Dom should always be learning more about everything that is associated with being the Master. To always be seeking knowledge is to be striving to perfect the art. And art it is.
A scene must be well planned, and well executed in order for it to be beneficial for both Dom & sub. You must know what you wish to accomplish and what tools and activities will be used to obtain the desired results.
Training a slave so that they are also fulfilled and happy is no easy task. Having a successful relationship with your slave requires much communication and understanding. Through these two things comes learning and improvement. If a Dom cannot communicate with his/her slave they will not be very good at being the Master. There is more to it than swinging a whip.
