Your name of Iisak has formed an independent, positive, and determined personality. You are serious and methodical. You are not easily influenced by the opinions of others, who may accuse you of being stubborn. Your loyalty to, and appreciation for, your family and friends are shown by what you do for them rather than what you say. In personal relationships, it is hard for you to express the appreciation and compliments that mean so much to some people. You are a realist with interests in mathematics and technical or scientific fields. It is difficult for you to visualize or theorize unless the ideas being presented are developed in a logical step-by-step manner. You could be inventive along scientific or technical lines. You work best alone, making your own decisions, and learning from your own experiences. Despite your loyalty to friends, your communication at times is stilted, too candid, and frank.
