Sorry if it sounds like I want to oppose here, @raj808, but I hear this argument very often, that it might be "essential for some personalities". I do not think so anymore. To my perspective it has nothing to do with personality but functionality. So yes, you i.e. need this for soldiers. Please tell me of one excample, only one, where it might be essential for personality. And I don't mean that it may not have helped. But I mean that it was school that actualy helped and not mentors she or he met. So yes, it is about sozialization. And we addressed this with a QOTW not long ago with @homeedders. Take care! !invest_vote
