Your first name of Issac creates a serious, thoughtful nature, shrewd, efficient, and business-minded. Determined and positive in opinion, you resist taking direction and advice from others. Being self-assured and self-reliant, you are naturally inclined toward operating your own business or pursuing opportunities where your sense of freedom would not be curtailed. Although you are extremely devoted and loyal to your family and friends, it is not in your nature to express emotional sentiments. You recognize the need, but feel a lack of fluency in verbal expression. You are practical and steadfast but at times too limited in your personal opinions and ideas. By nature you are serious, thoughtful, and studious. You are not overly ambitious, preferring instead just to seek stable, settled conditions which are adequate to meet your responsibilities. Health weaknesses of this name centre in the head, resulting in such conditions as either headaches, sinus problems, hay fever, or weak eyes. A tendency to worry far too much over obligations and responsibilities could lead to a disturbed mental state.
