Professionalism vs professional

Making choice of the business for the rest of the life, everybody wants to do it successfully. Therefore, a doctor wants to help as many people as possible; the mechanic plan to be the best mechanic in his city; the cook dreams about own restaurant. Everybody wants to be a professional. I`m going to describe professionalism how I understand it, and  when I consider myself a professional.
In my opinion, professionalism is being the best in what a person doing for money, so I expect that a doctor will diagnose me correctly, I really want to enjoy my professionally painted room as long as I want, and I order my medium rare stake to find pink juice when I cut it. In this case, making a result or final product of a job is the first and most important  mark of professionalism. Of cause, i can`t ignore issue of behavior, and , yes, to make others wait, being rude with customers,  or make a fight at work fallowing personal preferences are not demonstrate a person as a professional. But.... I would prefer rude doctor who can diagnose my illness correctly rather then polite and smiling one who prescripts pain relieve from "I not sure what it is but it will help".
I can say "a professional" toward myself when result of my job make people satisfied and leave me proud of what I`m doing. By the way, only people who really love their profession can become real professionals in their results and behavior as well.
