Hi, I am not sure if you are still seeking an answer to your question.
I would like to say I totally understand your question having been in your position, well not exactly, I am not in retail or in manager’s position anywhere, but the only similarity is not being caught.
I want to stop without being caught and I think of it in this way.
All the time I spend in the act of stealing and all the time I spend in using my stolen possessions is much less than the time I spend thinking about these things and these thoughts steal all the space I have in my mind for any creative or productive thinking to occur. I only have this one life, and even within that life I just have few decades where I am physically and mentally at my best to make a difference in my life.
I dont care if I ever get caught or not, just by being dishonest and knowing in my heart that what I am doing is wrong and living a personality that is different from what I portray to the people I know is a punishment. It is a punishment because I am constantly thinking about doing it and after-effects of this act and it has reduced my ability to do other meaningful things which I would have been doing if I was not caught up with stealing things. I can also see that repeated acts like these have reduced my ability to feel so many different emotions that I used to feel before-happiness, compassion, sadness, love, forgiveness, friendship, and the list goes on.
So by stopping it I will not be doing any store a favor but myself a favor because I will be living a more natural life, I will be close to my inner self and that way I will be close to natural way of being happy, even if I remain poor and can not afford expensive things I will be happier because I will be doing other things that I used to dream of doing as a child, and thereby accomplishing what my my true goals in this one life are. I am sure no one wants to be remembered as a shoplifter. And even if by stopping I do not become someone great, I will atleast have some self respect for being able to stop myself from going on a dishonest path. Because it is not all the things that I may possess define me but my conscience and my actions do!
I dont know how long my life is and it is not in my hands to control its length but it is certainly in my hands to make it a quality life, a life where I have enjoyed all my emotions to the fullest, where I have attempted to achieve my dreams, so that when I am old, I will have memories of my youth and adult life that I can cherish and not regret! Above all my present will be much more peaceful and definitely happier.
hope this helps (me and anyone in my situation)
