Your first name of Zelker has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. Exploring new areas on your own, or with a few close friends, holds definite appeal and offers a constructive outlet for your restless energy. If, for some reason, you cannot carry out your plans, you can experience deep moods of depression. You rebel at restrictions and are resourceful in unexpected circumstances. 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. Generally, you do not like to waste time on superficial conversation. 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. You become intensely involved with everything you plan to do, but the stress arising from frustrating obstacles or misunderstandings with others could prompt you to be intolerant and sarcastic in your expression, with breakdowns in congenial relations with family and friends a possible end result. This name spoils relaxation and contentment, the mental qualities necessary for good health.
