The name of Sintra 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. 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. You appreciate mental exploration into new ideas. You dislike monotony. You desire to be recognized for your efforts, and, if you feel you are being taken for granted, you are apt to become intolerant, critical, and complaining. Because of your definite ideas and opinions, you work best on your own, free from the advice or interference of others. You struggle with the requirement to soften your expression with tact and diplomacy and to consider the feelings of others. 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. Stress causes health weaknesses to centre in the senses of the head, or the nervous system. This quality can spoil friendships and create losses in the affections.
