Some speculation. Openness is a valuable thing because it allows you to say things that might be misunderstood–people don’t share your brain and can’t interpret exactly anyway. By stating the details of yourself and trusting they won’t torn to pieces allows you to BE a continually evolving person without hidden secrets, loyalties to “safe” behaviors or long nurtured toxic misconceptions.
Living the best and most inclusive life a human can is a trait of openness. Can it be that we carry our private fears and faults unnecessarily hidden? In the open they may be neutralized by everyone recognizing themselves in them. Not reduced to commonplace emotions but held up to a richness of self–a wonder of complexity.
