Your first name of Joaozinho has given you a quick, analytical mind. However, independence, positivity and the urge for action and progress are such strong forces in your nature that you find it difficult to control them. Also, you must guard against using indulgence as an escape. Although you are not demonstrative of your feelings in family relationships, you maintain a strong sense of loyalty. Any criticism from others causes you to retaliate cuttingly in self-defense. However you must beware of driving yourself to exhaustion as a substitute for relaxation. Once you have given your word and undertaken a commitment, you are completely steadfast in following through in spite of any regret or frustration you may later experience in doing so. Routine, monotony, and the responsibility of looking after details can have a similar effect. The effect of the nervous tension can appear in childhood as stuttering. In order to gain greater congeniality in your personal associations, you need to cultivate a more relaxed manner, greater generosity, understanding, and tolerance, and, above all, you need to avoid being too outspoken and self-opinionated.
