I don't know if this is irrelevant but for some reason I thought this quote was interesting. Any thoughts?

"In the absence of confidence, courage takes over. Confidence operates in the realm of the known; courage, on the other hand, operates in the realm of the unknown, the uncertain, and the fearsome: you cannot be a confident swimmer unless you once had the courage to lose your footing in deep water. Courage is more noble than confidence, because it requires more strength, and because a courageous person is one with limitless capabilities and possibilities. In the lonely hearts, ladies often specify that they are looking for a confident man, but who they are truly looking for is a courageous man."

I read this on an article about self esteem, it's not some pua stuff or anything like that btw.
