How can you be a professional and a good human being at the same time?

Professionalism should have absolutely no bearing on what sort of human being you are. I would go so far as to say that if you were to exhibit  the "requirements"  for  being a true professional then it follows that you would also be a good human being! It boils down to an individual's concept of what a professional actually is!!

To be honest being nice human being nothing to do with being proffessional. In my opinion if you are nice human being then you will be automatically proffesional, as peter said it boils down to an individuals concept of what a professional actually is
