Robert,  I leave to others to comment.

What I have said applies to my life....I am a Zen person who lives by FEELING and NOT PURSUING KNOWLEDGE which tends to muddle and confuse...
even wisdom falls short of personal experience, insight and intuition.  

I can quote many cases of great people of the past who were geniuses and the most intellectual whose lives were lived in suffering and tragedy---I think you knew such people.

Simplicity, humility, contentment, compassion, being childlike in innocence, wonder and appreciation of beauty, of grace, of gratitude.....this doesn't not require knowledge--
it springs from the pure fountain of the heart,
it is all we ever need for a happy and fulfilling life.  

Kindly share your thoughts--many thanks.
