The name of Jelmer creates an intense personal nature. Consequently you are a determined, strong-willed person who projects uncompromising individuality. Your obstinate traits, candid expression, and disregard for diplomacy have, at times, spoiled friendships and success in your work or business. There is a tendency for you to dominate others. Tension and frustration exact a heavy toll on your peace of mind and nervous system. Your tendency to become possessive and demanding could alienate those you are trying to help, or those who are in closest association with you. You try to add something new and different to whatever you undertake, and would eagerly set off into new fields. In all your work and activities you are inclined to be rather unsystematic and disorderly. Temper, indulgence, or dependence on medication could become serious problems in your life if you allow your feelings and reactions to overwhelm your self-control. Your health could suffer through disorders affecting the nervous system such as fits, strokes, palsy, or epilepsy, or through weakness in the senses of the head that result in headaches, sinus conditions, or defective hearing or eye-sight.
