One never can say, "I have enough tact." It is never enough. A real tactful person, having proved not to be tactful enough in his everyday life, finds more faults with himself than a tactless person. As one becomes more tactful so one finds more fault with oneself, because there are so many shortcomings: actions manifest themselves automatically, words slip off from the tongue, and then the tactful one thinks and sees that he did not do right. But as Saadi says, "Once it is done then you, thoughtful one, repent of it. This is not the time to repent, you ought to have controlled yourself first."
