Psychic profit and loss
Psychic profit and loss is an increase (profit) or decrease (loss) in the acting man's satisfaction or happiness. Psychic profits and losses are sensible, subjective, mental and purely personal. They can be neither measured nor weighed. They can only be felt or sensed. The psychic profit or loss derived from any action can be compared with that of another solely in terms of more or less.
