We are not usually aware of our blind spots, and infrequently take time to consider that we might be encountering one. Yet, leaving room for that possibility opens our understanding to new connections and creative solutions.
One way of illustrating areas that are known and unknown is the Johari window. Named for its creators, Joe Luft and Harry Ingham, this simple diagram divides a square into quadrants. The quadrants are labeled:
1) Things we know about ourselves and others know about us (Known Self)
2) Things we know about ourselves that others do not know (Hidden Self)
3) Things others know about us that we do not know (Blind Self)
4) Things neither we nor others know about us (Unknown Self) 
When faced with situations or people that confound you, practice not knowing what anything means. Be with your experience and that of others without analyzing or interpreting it. Just accept it as it is and allow it to unfold. If your judgments come up, be aware of them without evaluating them.
Be a Professional Unknower, releasing the belief that you have the answers, and opening to the mystery, insights and opportunities of your experience.
Practice this several times during the week, when you think you know what something means or when someone asks for your opinion. Ask yourself, “What is my experience like when it is free of the limitations I place upon it?”
