I was reminded of an excerpt from Guy Kawasaki's book "Enchantment" this morning...
People are not binary. People are not ones or zeros, smart or dumb, worthwhile or worthless. Everyone has strengths and weaknesses, positives and negatives, competencies and deficiencies.
Everyone is better than you at something. People who don’t accept others often think they are superior to everyone. But no one is superior to everyone in every way. You may be a rich investment banker, but the person you look down upon may be a great teacher.
