“Seneca would say that he actually pitied people who have never experienced challenges. ‘You have passed through life without an opponent,’ he said, ‘No one can ever know what you are capable of, not even you.’ Epictetus said when a challenge is put in front of you, think of yourself as an athlete getting paired with a tough competitor. You want to be Olympic-class? ‘This is going to take some sweat to accomplish,’ he said.”
