Your first name of Calder creates a quick, clever mind capable of grasping and assimilating new ideas. You tend to be studious, analysing each new idea before accepting it. Associating with your own age group often does not hold your interest and you tend to seek the stimulation of minds more mature than yourself. You work best on your own in fields such as with the products of the earth, real estate, or computer sciences, as long as you have the freedom to make your own decisions. You have a sensitive nature--sensitive to your environment and particularly sensitive to how your deeper and more serious interests are regarded by others. This characteristic could make you rather unpopular with your associates. Your feelings are very easily hurt and to protect yourself you withdraw within the realms of your own private thoughts and shut out the rest of the world. For your interest to be retained you need to be mentally challenged; this was most evident when young and in school. Your sensitivity and lack of verbal expression frustrate and limit the satisfaction in life to be gained from your responsible and capable nature. Moods, which are your worst enemy, result.
