Your first name of Itzchak creates a serious, thoughtful nature, shrewd, efficient, and business-minded. Determined and positive in opinion, you resist taking direction and advice from others. You can be depended upon to do any job well and you will often carry out an undertaking yourself instead of accepting a second-rate job by someone else. In times of need, others are drawn to your forthright, matter-of-fact manner. You are one to make your own decisions, and not be influenced by others. Having everything under control is important to you to demonstrate your capable, serious nature. Your accomplishments give you a great deal of satisfaction, and involvement in social activities can sometimes make you feel that you are wasting time. Situations requiring sympathy and understanding, or where compliments are expected, may make you feel awkward and embarrassed. In your personal relations with others, you are inclined to be rather serious, and not to see the humour others see, or to respond spontaneously. Health weaknesses of this name centre in the head, resulting in such conditions as either headaches, sinus problems, hay fever, or weak eyes.
