Ready To Be Wrong
When solving problems it is inevitable that a proposed solution will not meet the necessary requirements. When groups communicate it is inevitable that a miscommunication will occur. When you recall information it is inevitable that you will misremember. Being wrong is not a niche occurrence and should not be treated as one. Rather, being wrong effectively is a skill worth learning, allowing for faster course correction and a more helpful, productive work environment.
An incorrect answer is an opportunity for a correct one, but all involved parties must be prepared to confront an answer's potential incorrectness. Initially, this is the most difficult part of the process. Once understood that exploring more correct answers and accepting previous ones may have been incorrect, a more important question can be regularly posed: Am I wrong? Consider that you may be and the knowledge that can be gained from understanding when you are.
Be ready to be wrong.
