Your first name of Casby has given you a quick, analytical mind. In your dealings with people you place great importance in living up to one's word. 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. You are happy and in good spirits as long as headway is being made, but as soon as you feel obstructed or your individuality and freedom of action are curtailed, you experience an intense nervous reaction in your solar plexus. 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. Family and friends find it hard to understand you because of your changing moods, and because of your intolerance and indifference towards their ideas, interests, and feelings. Your nervous intensity could cause indigestion and, over time, could lead to ulcers and severe stomach problems. 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. 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. 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.
