I think professionalism is not just being good at what you do but it has alot to do with how you do it. Like your character, not being lazy, being prompt, not being rude and if you are angry with a co-worker or employee or even your employer, tell them what upsets you or what isn't acceptable and be a good role model by doing this in an appropriate manner with out screaming or swearing. Your character makes you a professional, not your job or career.
