The name of Yas 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. You have a tendency, at times, to have too many ideas on the go, and thus your efforts are scattered and many things do not reach completion. You appreciate mental exploration into new ideas. Thus, you have too often created the wrong impression, and friendships have suffered. 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. Your obstinate traits and candid expression have, at times, spoiled friendships. You have your own strong opinions and it is not easy for you to be influenced by others to change your mind once you have reached a decision. You dislike monotony. 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.
