I read about "Highly Sensitive People" today and concluded that this "epidemic" must be prevalent among the design community. It means you are aware of subtleties in your surroundings, a great advantage in many situations. For example, perfecting the look and feel of an interior, ha. It also means you are more easily overwhelmed when you have been out in a highly stimulating environment for too long, bombarded by sights and sounds until you are exhausted. Ask yourself the following questions, maybe you'll reconsider your profession, ha:

Are you easily overwhelmed by such things as bright lights, strong smells, coarse fabrics, or sirens nearby?
Do you get rattled when you have a lot to do in a short amount of time?
Do you make a point of avoiding violent movies and TV shows?
Do you make it a high priority to arrange your life to avoid upsetting or overwhelming situations?
Do you notice or enjoy delicate or fine scents, tastes, sounds, or works of art?
