the brain and nervous system constitute a marvelous and complex “goal-striving mechanism,” a sort of built-in automatic guidance system which works for you as a “success mechanism,” or against you as a “failure mechanism,” depending on how “YOU,” the operator, operate it and the goals you set for it.
Your brain and nervous system work together to accomplish goals you set, consciously or subconsciously, these goals can be percived as succsesful or unsuccessful.
