The quotes are good. And your points are valid. My point is simply that someone with very low confidence cannot grow it by failing, if failure (and their belief of how others perceive that) is what they fear, especially if they are to fail pretty miserably. For someone with even moderate confidence, there are many competitions where failure is pretty safe (psychologically speaking) - like from what I've seen at most BJJ, Judo, and Karate competitions. But that only works if the subject correctly perceives the outcome. If they see a failure as devastating (people think less of them, etc.), then it doesn't actually matter much how positively others respond. Their fear feeds itself.Fear of losing, fear of failure. That's the piece. Sorry I used a politically incorrect word.
The key issue here is one of resilience. Confidence isn't a trait; it is a by-product. It's a result. Fear is the real issue here. The only way to overcome fear of failure is to fail and realize that failure is a necessary function of growth. Success is validation; failure is growth.
I didn't say competition is the only, or even the best approach for all folks. However you fail, you need to do it.
Now, competition is the only way people can gain access to some other things. But failure is available in many ways.
And sure, it's hard. And sure, it's harder for some than others. And of course, the longer you live with fear of failure, the harder it will be to overcome it. None of that changes the situation in the least.
"Ever tried. Ever failed. No matter. Try Again. Fail again. Fail better."

"I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times I've been trusted to take the game winning shot ... and missed. I've failed over and over and over again in my life. That is why I succeed."
~ Michael Jordan
"I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when my fear is gone I will turn and face fear's path, and only I will remain." - Maud Dib
That said, I do think competition is a great part of the process. Perhaps not the starting point for some folks. And team competition seems to be more help for folks who are struggling the most (where they can feel more protected from the exposure of loss).
