The ability to make that decision on what your Master will and will not make you do is paramount.  That trust factor to obey without question...to carry out His instruction without worry,  with concern, but quickly and to the best of your ability because you trust Him and have faith in his guidance 

So many people do not understand the ability of growth within the lifestyle as His submissive.  If she is not growing, then he is failing.  If she is happy being stagnant, then He will increase her desire for success.  A good Master should always have a list of things that His submissive wants or needs to improve about herself and He should ensure that she is on the right path to obtain it.  He has to be able to learn from her as well and she cannot accept it and/or view it as weakness, but rather an overwhelming strength to ask and desire her opinion and guidance as long as it is spoken with respect and servitude. 

When you are committed to your Master, you will not go and find sexual gratification due to His lack of time to be with you, but rather desire Him more due to his absence and want to please Him in all ways desired by Him when you have the opportunity to because you know what you are learning, gaining, and becoming a better you for you and for Him.
