Your first name of Sinya has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. You could experience a great deal of pleasure in outdoor physical activity or sports. Therefore, if anyone interferes with your activities or offers unsolicited advice, you are inclined to react defensively and express your feelings in a blunt and, at times, caustic manner. You rebel at restrictions and are resourceful in unexpected circumstances. When you are annoyed, you must guard against a strong temper and the expression of intolerance and criticism. 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. 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 appreciate nature and the freedom associated with being in a natural environment. 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.
