“Many of us have been persuaded that happiness is something that someone else, a therapist or a politician, must confer on us. Stoicism rejects this notion. It teaches us that we are very much responsible for our happiness as well as our unhappiness. It also teaches us that it is only when we assume responsibility for our happiness that we will have a reasonable chance of gaining it.”
