Your name of Jack gives you a strong urge for independence. You can express yourself with greater ease in writing. Your name often makes you feel separate and alone. You stick stubbornly to your ideas or decisions, in spite of any appeals or advice; you are not willing to accept a compromise. You are steadfast and loyal, and do not allow gossip or anything belittling to be said against those whom you accept in friendship. Your friendships and personal associations are rather restricted, being limited to those of a similar nature who can understand and accept your rather straightforward yet reserved manner. You find your own solutions and innovations to get a job done, without relying on encouragement or assistance from others. As a result, others withdraw from you as they find you to be somewhat severe, aloof, and uncommunicative. You find satisfaction in being outdoors or in getting out into nature, or in dealing with the products of the earth. There is originality and depth of thought contained in this name, particularly along practical and mathematical lines.
