Benjamin Franklin, one of the legends of American history, although he had only a few years of formal education, became a famous printer, musician, author and scientist. He participated in the establishment of a country and was a diplomat. When he was twenty years old, he set himself the goal of attaining moral perfection. Thus, in order to achieve his goal, he placed thirteen virtues he practiced every day. In order to remain consistent in his training, Frankline wrote all the virtues in a small book that he constantly carried with him, which had seven columns for each day of the week, and thirteen lines for each virtue in particular. In order to be as successful as possible in training, he evaluated himself for each virtue in the end every day. He put the spot next to every virtue that he broke that day.
