Your first name of Jirka has made you a hard worker with a meticulous sense of detail. You are more interested in being active and accomplishing the tasks you set for yourself. You are stable, trustworthy, homeloving, and logical in practical matters, but rather unresponsive to suggestions from others. You are rather skeptical of new ideas that are more visionary, idealistic, or philosophical. Once you have made a decision, you put forth great effort to accomplish your goals regardless of obstacles. You do not have great ambitions and your requirements in life are moderate. It is what you can see, experience, and prove through compilation of facts, experiment, and logic that has greatest value to you. You are not easily influenced by the opinions of others, who may accuse you of being stubborn. Also, your fondness for heavier foods can affect the intestinal organs causing constipation, hemorrhoids, and even in severe cases, ulcers or growths. This name limits your vision and imagination but you could be inventive along practical lines.
