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.

A reasonable use of your nerve force, like a reasonable use of the rainwater, means you can maintain a permanent supply. But you must be reasonable; you must give the cistern a chance to refill and replace that which you have drawn out.

You, who have shattered and tattered your nerves, are not hopeless. You can come back, but it must be done by complete change of the acts that brought on the condition.

Get more sleep. Eliminate the useless, harmful fads, fancies and functions which disturbed and prevented you from living a sane, rational life.

Avoid extremes, cultivate rhythm and regularity in your business and your home life. Keep away from excitement. Read really good books. Walk more, talk less.

Eat less heat-making foods and more apples. Follow the diet, exercise and thought rules suggested in "Pep."

Maybe these lines are being read by a discouraged one who is "all nerves," which means lost nerve force. To you I say there is hope and cheer and strength and courage if, right here, now, you resolve to cut the actions, habits and stunts that knocked you out and follow my suggestions.

I know, my friend, for I've trotted the heat, danced the measure, and been through the mill.

Now I am fearless, calm and prepared. I can stand any calamity, meet any issue, endure any sorrow.

I can do prodigious work in an emergency, go without rest or eating when required, because I have poise, efficiency—peace.

I realize nothing is as bad as it is painted. Nothing is as good as its boosters claim. I go in the middle of the road, avoiding extremes. I have confidence in my heart. Courage, hope, happiness, and content attend me on my way.

I've buried envy in a deep pit and covered it with quick lime.

I am keeping worry out by keeping faith, hope and cheer thoughts in my brain-room, and these are antiseptics against the ravages of the worry microbe.

I have my petty troubles and little make-believe worries, just enough of them to make me realize I have them licked, and to remind me I must not let up on my mastery of them.

Worry growls once in a while just to make me grab tighter the handle of my whip.

And you may enjoy this serene state, too. There is no secret about it. I will gladly give you the rules of the game in this book. Just prepare to receive some practical, helpful suggestions.
