So highly did we regard the work that the president of this company, over his signature, contributed an introductory note of endorsement, citing his own experience in following the rules and principles laid down in PEP for the attainment of "poise, efficiency and peace." Our confidence and belief in PEP were amply justified. Eight large editions were printed in four years. Over 70,000 copies have been sold. THINK--the last book that Colonel Hunter wrote--is now published for the first time. It is especially important, coming, as it does, at a time when commonsense thinking, good health, good cheer, optimism and rational methods of living are more necessary than ever before. In this trenchantly written volume, Colonel Hunter has given some golden advice to the man or woman who is facing the big problems of to-day in a wavering or hopeless spirit. Correct your thinking. Get a grip on yourself. Colonel Hunter tells you how. THINK 1. We all enter the world with an abundance of nerve energy, and by conserving that energy we can adapt and adjust our nerve equipment to keep pace with the progress and evolution of our times. The way to preserve and conserve nerve equilibrium and power is to rest and relax the nerves each day. You may rest them by a change of the thought habit each day, by relaxation, by sleep, and by the suggestions made in this book. There are but few advance danger signals shown by the nervous system, and in this there is a marked difference between the nerves and the organic system. If you abuse your stomach, head, heart, lungs, liver, kidneys or eyes, you have distress and pain. The nervous energy is like a barrel of water--you can draw water from the faucet at the bottom until you have almost exhausted the contents. Nature mends ordinary nerve waste each day, like the rains replenish the cistern. [Sidenote: Conserve Your Energy.]
