Whew!  What a banquet of ideas!  Like looking into a crystal - watching colored lights dancing in the most unexpected ways. Lex, I (with my PhD black belt in tow) found your treatise on being an expert tempts the holder to inflate the ego and lessen further curiosity. As I’ve heard it said, ‘the road to success is constantly under construction’. With deep gratitude for all you do to mine the mind, Cliff Rodman.
