Learning contains much failure, and being able to better control your own emotional state in the presence of these many every-day failures makes further progress faster, easier, and more pleasant for everyone?
Meanwhile, what did I do? I learned to stop crying by quitting Karate. I didn't actually learn to process my feelings. I just learned how to either repress them, avoid them, or lie about them.
That's not control, because all of that was accomplished subconsciously. Control relies on self-awareness. And repression isn't pleasant, certainly not in the long run.
I'm not trying to get all touchy-feely here. I think self-awareness about one's emotional state is a vital survival strategy.
That isn't to say that some negative emotions are better ignored, but I have a pretty strong inclination to avoidance over confrontation, and it's hard to know if I'm ignoring something that isn't worth my time or unable to confront something that's going to fester.
I think it's ultimately all about efficacy. I've interacted with a lot of people who believe themselves to be totally regulated and are actually seething with resentment. Some of those people are in my family. I know I don't want to live like that. I'd like to think I've got a better model, but only time will tell.
I guess I just find the whole human emotional landscape to be extremely complex and nuanced, and most of the people who I meet who believe that all negative emotions can be regulated away are just pathologically unselfaware. If the alternative is navel gazing, I'll take it.
Kids learn soon enough what the real boundaries of their emotional life are. As a little boy, I was told that it was weak to cry if I lost a Karate match but as long as I lied and said it was because I got punched really hard, it was OK. I'm not sure what the ultimate goal is of this kind of socially engineered lack of self-awareness, but it doesn't seem to be working. At least not for me.
