Your first name of Sendel has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. The repression and frustration that you may experience at challenging moments in your life cause nervous indigestion and, in the worst cases, could result in ulcers and severe stomach problems. It gives you the desire to be a leader, to pioneer new undertakings, and to try new ideas in practical, creative occupations. Over-intensity is your challenge; you put a great deal of effort into your activities, but often fail to take time to relax, to view your plans objectively, and perhaps, to consider the opinions of others. It makes you self-sufficient and self-reliant. Exploring new areas on your own, or with a few close friends, holds definite appeal and offers a constructive outlet for your restless energy. Lavish displays of emotion tend to embarrass you, making you feel self-conscious and inadequate. You expect a great deal of yourself and of others, and you are seldom satisfied with your accomplishments. Intensity affects the senses of your head as well, whereby you could suffer with migraine headaches, sinus problems, or throat and swallowing difficulties. This name spoils relaxation and contentment, the mental qualities necessary for good health.
