Pain
Pain is what we encounter when our potential is bursting to the surface. We want to express it, but we look within, and something there causes us a wide range of unpleasant things and unpleasant reactions.
Pain fuels our desires; desires exist to heal our pain, and they feed on pain. Therefore, a person who has treated their pain with a psychologist has lost their fuel and most often become dull, inconspicuous, simple, rational, and joyless, but has freed themselves from everything.
