?'s are the most important thing.

I just finished reading Change your Questions change your life.  It is an interesting book which is all about a questioned centered approach to life. 
For many people this might sound frightening as it presumes they don't have answers.  From my perspective there is nothing more interesting or intriguing than a good question.  A question centered approach to life allows one the ability to learn, listen and grow.  It also implies a degree of humility and ignorance.  Acknowledging ignorance is a far more powerful position than positioning oneself via expertise. 
The most interesting and best scientists, leaders and managers I have worked with always had questions curiosity and a desire to discover and learn.  Experts fear being "found out" to not have all the answers.  If you have a chance pick up the book Change your Questions change your life, it is a fun read.  Its proposition is to not judge, but to question and then listen others and yourself.  This falls very much in line with Carol Dwecks' excellent approach to leadership and education.    Learning, listening and questioning makes people far more interesting and capable to lead and grow.   I have two ears and one mouth, I try to use them proportionally.
