So if taking a beating makes you stronger and shows what a strong person you are, why are you not still abusing your body? 

Oh you grew up and realized that getting hurt sucks. You sound like someone that takes joy in the pain of others. Through some sadistic urges you feel the need to abuse children based on a pattern of abuse that you yourself suffered. 

Equating the ability to deal with pain with your stature in society is a BS game that adults play with children, even when if it was you with the bad enough scraped knee you would be at the hospital asking for pain killers, or do you think it is the kids that are hooked on opiates?
