Often we imagine that we will work hard until we arrive at some distant goal, and then we will be happy. This is a delusion. Happiness is the result of a life lived with purpose. Happiness is not an objective. It is the movement of life itself, a process, and an activity. It arises from curiosity and discovery. Seek pleasure and you will quickly discover the shortest path to suffering. Other people, friends, brothers, sisters, neighbors, spouses, even your mother and I are not responsible for your happiness. Your life is your responsibility, and you always have the choice to do your best. Doing your best will bring happiness. Do not be overconcerned with avoiding pain or seeking pleasure. If you are concentrating on the results of your actions, you are not dedicated to your task.
