I listen and see.  My sight is clear and my mind is open.  I have been lucky to know so many brilliant  people (and I do not mean necessarily  PhDs, MDs, etc) in my time on this planet.  I do mean brilliant  people who have taught me while I have watched, listened and engaged with them.  I have learned from everyone.  For me, this is skill, my skill,  has allowed me and others to become more well  rounded and open to all the possibilities.
