Your first name of Johna has made you happiest when you are expressing in some creative, artistic way, and not conforming to strict routine. You are happiest when you are expressing in some artistic way, free from monotony and detail. Occasionally, when you are unhappy or disappointed by something, you can be moody and temperamental, and feel misunderstood and unappreciated. A very individual, independent person, you live within your own thoughts. However, self-consciousness, at times, prevents you from feeling at ease in positions of impromptu self-expression. On the other hand, among friends with whom you feel at ease, you are expressive, witty, and quite charming. You love to argue and can be strong-willed, but you are easily hurt by the comments of others. In a large group of comparative strangers, you are quiet and rather shy, unable to express yourself, not really wanting to become involved in conversation. Over-indulgence could cause a weak back, skin conditions or arthritis later in life. The heart and lungs could also be affected at stressful times.
