No I think you explained it quite well. Also, I don't look at confidence or one who is happy with oneself an interpret that as ego or arrogance. I am not the most secure person in the world but I am rational.

I'm practically the opposite of how you just described yourself. Although I have a few unusual and innate strings to my bow and come across sometimes as arrogant to people I am quite insecure and don't think that much of myself. Most people who know me wouldn't think I felt like that cos I have a varying skill set and I speak my mind in life. Doesn't mean I think I am that great a human being though. I've been bitterly disappointed in myself on many many occasions!
