You like to organize your intellectual life into a system. This gives control over your thoughts to such an extent that, when you need to react to the issue in hand, you can retrieve the desired response from your mental filing tray. Such control, though perhaps too clinical by someone else’s standards – as it can preclude mental passion – is nevertheless quite an intellectual achievement in itself.
Your mind is serious, exacting, patient and orderly plus you have the ability to concentrate on deep subject matter. With this ability comes a tendency to depression, pessimism, loneliness or despondency. You have organizational ability and are probably conservative and traditional in your thinking. Mathematics and strategy games may appeal to you. Time consuming projects do not bother you. You may feel a bit isolated from siblings and neighbours or they may give you trouble. There may be issues of communication with either. Try to stay optimistic in your thinking and in the meantime simply keep working hard. Your lungs need plenty of oxygen, so try to sleep in a well-ventilated room.
