You are introverted, reserved, calm and low-key.  You are easily overstimulated and avoid busy and noisy environments as you find them to be overwhelming.  You keep your social life fairly simple, as you may find dealing with people saps your energy and is often unrewarding. You often find it difficult to express yourself and may prefer others to do the talking.  You are generally calm and not easily excited about life.  You might realize you are less motivated than other people to achieve things like money, status, adventure, romance, or popularity.
