Openness

Always be open. Open to learn. Open to change. Open to a new direction. Open to feedback. Open to something that totally contradicts what you know to be true.

The simple fact is you don't have all the answers.

You have a very unique worldview. It doesn't stop there. Because so does the person giving you feedback.

Embrace others perspectives, they are the people that buy your time, purchase your product and transact in your stores. 

Be open. Be flexible. Own humility, not as a buzz word but a way of life. You are not the authority on others experiences only your own.
