However you must beware of driving yourself to exhaustion as a substitute for relaxation. You feel happy as long as headway is being made, but as soon as you are obstructed or your individuality and freedom of action are restricted, you experience an intense nervous reaction. Moods of depression can result during which you become caustic and belligerent in your attitude toward everyone, especially to those in closest association with you. Although you are not demonstrative of your feelings in family relationships, you maintain a strong sense of loyalty. Competitive sports or challenging outdoor activities could bring you pleasure and relief from pent-up frustrations. This name creates a desire to be a leader, to pioneer new undertakings, and to try new ideas in practical, creative endeavours that provide an outlet for your versatility and imagination. The effect of the nervous tension can appear in childhood as stuttering. Routine, monotony, and the responsibility of looking after details can have a similar effect on you, as you are a person who desires change, travel, and new experiences.
