The name of Clark creates a dual nature in that you can be very generous and understanding, but you can also be so candid in your expression that you create misunderstanding. Difficulty in accepting advice or admitting that you may have made a mistake causes you to appear to be stubborn and set in your ways. At times, you are an extremist in whatever holds your interest, with the result that you focus all your energies, your ingenuity, and originality of thought to do your best. Learning to withdraw, particularly in the outdoors environment, can bring a sense of peace and relaxation for you as you occupy your thoughts with the beauty and phenomena of nature. Overtaxing your nervous system by being under too much pressure brings about your temperamental reactions. Independence and freedom of action mean a great deal to you; therefore, you enjoy positions where you are giving instructions rather than taking them. You appreciate mental exploration into new ideas. You could develop a dependence on medication, for example, to relieve the tension. Stress causes health weaknesses to centre in the senses of the head, or the nervous system. If you allowed it, temper and self-pity could be problems.
