Yes, you read it right guys. Want to grow and become a more confident/centered person? Go and do things that will challenge your perception of yourself and fight the battle vs the ego. The reason some people struggle getting ahead in life is they're afraid to embarrass themselves. You get blown out by a girl and you right away start berating yourself and all you can think of is how horrible it felt and how all the people who saw are making fun of you and how you can never show your face again. This is what AA is just another of life's little defense mechanisms. What you should really be doing is laughing the that shit off, and always going out and bruise the shit out of your ego. Show that mother fucker who's the boss of your body, show it you are not afraid of being rejected by a stranger. Thats what builds mental toughness. Eventually you won't even sweat the simple stuff.
