I'd like to add to this discussion by sharing a thought. I am not a 121 guy, so take it for what it's worth. Originally this was in reference to another subject but I feel it applies to professionalism as well. It came from a highly experienced, wise aviator.

"I am of the opinion that pilots are not allowed to rationalize, not if they want to live. They have to analyze, accept and move on one notch smarter. In order to be able to do that, we have to accept in all honesty and clarity exactly the nature and severity of the mistakes we made. In being honest with yourself, you will find strength and value. When we start to rationalize and delude ourselves we set ourselves up for future failure and the cycle of low self worth and the developed self pity continues and you spend a lot of money and still don't find what you came to aviation seeking."

... I see a connection. Do with it what you wish.
