Your first name of Zilka has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. You work best alone and are happiest when expressing your many ideas creatively in an area that offers flexibility and challenge. You could experience a great deal of pleasure in outdoor physical activity or sports. You attend to tedious responsibilities only when you have no other alternative. If, for some reason, you cannot carry out your plans, you can experience deep moods of depression. When you are annoyed, you must guard against a strong temper and the expression of intolerance and criticism. You appreciate nature and the freedom associated with being in a natural environment. Because of the restless qualities within your first name, it is very often difficult for you to find pleasure in ordinary congeniality. While you are creative, inventive, and ingenious in practical matters, and always ready to initiate and promote new undertakings, you often experience difficulty in bringing your undertakings to a successful conclusion because of your own changing interests or changing circumstances. 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.
