They fancy and insist that they know all things, and this is why they overdo everything. Chilon, Nothing in excess Democritus, Everywhere man blames nature and fate, yet his fate is mostly but the echo of his character and passions, his mistakes and weaknesses Democritus, Happiness resides not in possessions and not in gold, the felling of happiness dwells in the soul Epictetus, Men are not worried by things, but by their ideas about things. When we meet with difficulties, become anxious or troubled, let us not blame others, but rather ourselves, that is, our ideas about things.
Nature demands little, opinion a great deal.
