Your first name of Theiler has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. It makes you self-sufficient and self-reliant. Your love for others is shown more in your loyalty and sense of fair play rather than in any overt demonstrations of love and affection. As it is difficult for you to express the little attentions and niceties that appeal to more sensitive natures, you attract misunderstandings with those who do not appreciate your forthright manner. You appreciate nature and the freedom associated with being in a natural environment. When you are annoyed, you must guard against a strong temper and the expression of intolerance and criticism. 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. You work best alone and are happiest when expressing your many ideas creatively in an area that offers flexibility and challenge. 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. This name spoils relaxation and contentment, the mental qualities necessary for good health.
