What is confidence anyways?

"When a beautiful woman walks into a room, I may glance up for a moment, but I soon return to my entree or my conversation or the dessert menu. Let's be honest: beauty is not all that interesting (and certainly not more interesting than the dessert menu). But when a confident woman walks into a room, it is entrancing. I'll watch as she moves with poise and self-possession. She is not usually the one in the plain black dress. She is the one in the interesting shirt and vintage skirt, and I immediately want to know where she got them. And she may not be the most stunningly gorgeous woman I've ever seen, but she has a way about her that can make her one of the most intriguing. Confidence is captivating, it is powerful, and it does not fade- and that is endlessly more interesting than beauty." From The Little Black Book of Style by Nina Garcia
