Your name of Callisto makes you independent, self-reliant, and determined. You could excel in scientific research because of your ability to concentrate and remember details, or you could be inventive along practical, mechanical lines. You enjoy practical creativity which calls upon your originality and ingenuity. It is challenging for you to reveal your deeper thoughts and feelings, as you tend to be self-conscious, reserved, and secretive. Although you tend not to like crowds and social activities, there are occasions when you feel lonely and misunderstood. You are earnest and studious, but can be stubborn and fixed in your ideas and opinions. You desire affection and understanding but often leave the impression that you want to be left alone. You are quiet and gentle mannered as a rule, preferring silence to argument and turmoil. This name would cause tension in the head through troubles with either eyes, teeth, sinuses, ears, or throat or cause headaches. The insecurity you experience from limited verbal expression and social ease results in a jealous possessiveness and suffering through frustration, repressed emotion, and self-consciousness.
