Epictetus was a Stoic philosopher in ancient Greece. Born a Roman slave in 50AD, Epictetus would go on to become one of the most sought-after philosophers of his time. This memento is a wonderful reminder to practice gratitude. A person who constantly ponders what they *wish* they had will never find contentment, whereas the person who notices and appreciates all that he has will regularly be joyful. The Stoics encouraged practicing negative visualization—frequently imagining losing all the things you currently have—in order to cultivate joy, appreciation, and contentment for *how things are now*, rather than longing for some hypothetical future.
