Indeed all those qualities are required & a professional becomes a professional by the way he does his work, how he conducts himself & more importantly the explanations he gives to the work that he does tells clearly about how much professional he is.
Passion is something that also makes good & happy professionals & they are more or less better than serious professionals I feel.
When one works with passion, one derives the best results which is the focal point of being a professional.
Life is like a boat in a sea, there is a lot to learn, so never close your mind to your limited experiences!
