"During his term as President of the U.S., Lyndon Johnson was somewhat overweight. One day his wife challenged him with this blunt assertion: "You can’t run the country if you can’t run yourself." Respecting Mrs. Johnson’s wise observation, the President lost 23 pounds." And yet this story not only suggest that our ability to control the self is possible, it suggests that it is within us.
