CHAPTER VIII.
Vacillation and doubt are poison to the nerves.
This is the reason why it is advisable to teach co-ordination, prompt response to the command of the brain over the muscles, and the general sense of self-control which comes to a man when he has only to think in order to turn that thought into quick action.

One of the penalties of the executive position is that, although the man begins as a disciplined private, when he goes up higher and gradually reaches the point where he gives commands only, and never has any practice in obeying them, he gets the habit of pushing buttons to make other people jump, while there are no buttons pushed to make him jump.
WORRY AND FEAR Now as to worry.

It has been said, and not untruly, that one of the very largest causes of worry is bodily weakness.

And in more than a majority of cases this weakness comes from poor physical condition.

A good digestion and proper elimination seem to make the organism move smoothly, not alone with muscles, but with nerves.
