Some seem to think that the heart is what cuses all the problems because having emotional responses to things apparently precludes you from being able to logically and rationally deal with it. I kind of like to pretend there's room for a full range of stuff to happen while dealing with a problem, not entirely emotional, not trying hard to pretend to be a Vulcan ;D
But yes, I'm with you, that need to be right can be scary especially when it comes at a cost of learning something new or fixing something that's actually causing problems.
