man-made, or natural that are work enhancing aids. Phenomena-type
techniques, like visualization and hypnosis also fall into this
These items and practices are done in the belief that they will improve performance beyond that which could be achieved by traditional training methods alone. Some consider these to be more like superstition than actual science. We, however, believe that as long as it doesn't hurt, it is worth a shot. And, if it enhances your mental state by making you believe that you will succeed, then it is certainly worth trying!
