The Power of Concentration is an in-depth series of chapters devoted to the use of our memory system; as the title suggests, how to develop our memory system, how to train it to improve it, and how to make the best use of it in our everyday lives, and to improve our positions in life. This is not intended to be a series of chapters to impress friends and colleagues, nor to play 'tricks' on others, rather it is for the betterment of individuals in whatever walk of life in which they may be involved by training and using their memory toward that end.
