Your first name of Zack has given you a quick, analytical mind. 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. You expect as much from others in return but find, either through misunderstanding or lack of principle in others, you are often let down, leaving you feeling bitter and betrayed. In your dealings with people you place great importance in living up to one's word. Moods of depression often result as well as outbursts of temper, caustic remarks, or a belligerent attitude towards everyone, especially those closest to you. Also, you must guard against using indulgence as an escape. Other fields always look greener, with the result that you experience a great deal of dissatisfaction with your present circumstances. 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. 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. The effect of the nervous tension can appear in childhood as stuttering.
