Your first name of Iisac has given you a quick, analytical mind. Competitive sports or challenging outdoor activities could bring you pleasure and relief from pent-up frustrations. Also, you must guard against using indulgence as an escape. 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. Although you are not demonstrative of your feelings in family relationships, you maintain a strong sense of loyalty. Your great initiative and driving power would enable you to excel in sales and promotion, and could take you far in business success, but you must guard against losing interest once your initial enthusiasm in a project wanes. The urge for action or progress is such a strong force in your nature that you find difficulty in controlling it. You are creative, versatile, and imaginative. Ailments could also centre in the head causing headaches, sinus problems, or defective eyesight, hearing, or teeth. 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.
