Right and wrong are distractions
People are right or wrong with opinions or conclusions, but this just reflects back to the person. At best, this may be true for the moment, but this is never enough because the moment is now over. At worst, "right and wrong" frame of mind is a dead-end for discovering best solutions.
Right versus wrong is also a slippery slope leading to traps such as the blame game - also counter-productive. What’s done is done. Move on and focus on solutions, not the past or finger-pointing. Translated, this means that good leaders and team members doesn’t piss off others by venting and pointing out deficiencies. Briefly discuss to identify what could have happened to improve results, and then quickly move on and focus on fixing, solving, and the best path forward.
Who’s right and who’s wrong is also irrelevant. Needs, opportunities, and other data points create the landscape for whats possible, but then the focus needs to be on assembling and prioritizing the set of traits that can be accomplished or steps to be performed to deliver exceptional results.
