For instance, the name "Master."
There are many definitions of that particular word, for the purposes of this discussion, let's consider it indicative of a level of expertise due to extensive study and practice or education slightly less than that required to hold a doctorate. Or, as in my trade, I hold the title Master, considered capable of any task in the field.
How does one become a Master? Practice, study, study, practice, study, practice, finally, look at what you have created... is it the work of a Master? You decide, and hopefully, others will concur. If they do not it's time for more study. "What????" you say, "I've done my time!!!! I don't need to study any further."
Ah... and who is going to bestow the elusive title of Master upon you? Do you place it on yourself, after all, who's going to know? What's in a name anyway.
What's in a name is reflective of who is going to take action due to the name, and what action they are willing to take. You see you can call yourself whatever you want to. You could be Dr. Phil if you want, the issue is, if you say you are Dr. Phil and someone takes steps to follow your diagnosis of their psychosis, and they crash horribly... because you were not Dr. Phil at all but rather some wannabe Dr. Phil. What do you do with the responsibility for the damage you cause?
I was talking to a submissive on another site who shared a horrible experience with me about an experience she had with someone who called himself a Dom. He said all the right stuff, and they were going to visit a dungeon, not more than a million miles from here, so they could do a scene but, at the end of the day, since the dungeon was in a different city, and they were tired they decided to just do the scene at his house. Once he had her tied securely to the bed, he began to flog her, then his enthusiasm increased as the flog continued relentlessly, she became alarmed as her safe word brought no respite. A glance over her shoulder into his eyes revealed a madman who was away with the fairies, the very bad fairies. To quote her; "He totally lost all control, beating me, I saw the blood flying and he showed no signs of stopping until I was screaming hysterically, crying and snotting all over, he finally stopped, leaving me badly beaten."
Sadly, that was the last conversation I ever had with her, I would like to think that she simply moved on with her life.
