Pythagoras used to say that life resembles the Olympic Games: a few people strain their muscles to carry off a prize; others bring trinkets to sell to the crowd for gain; and some there are, and not the worst, who seek no other profit than to look at the show and see how and why everything is done; spectators of the life of other people in order to judge and regulate their own.
Michel de MontaigneIt takes strong ears indeed to hear ourselves judged frankly, and because there are few who can endure criticism without being stung by it, those who venture to criticize us perform a remarkable act of friendship. For it is a healthy love that will risk wounding or offending in order to profer a benefit.
Michel de Montaigne
