_Don't Talk_ THERE is more nervous energy wasted, more nervous strain generated, more real physical harm done by superfluous talking than any one knows, or than any one could possibly believe who had not studied it.

I am not considering the harm done by what people say.

We all know the disastrous effects that follow a careless or malicious use of the tongue.

That is another question.

I simply write of the physical power used up and wasted by mere superfluous words, by using one hundred words where ten will do--or one thousand words where none at all were needed.
I once had been listening to a friend chatter, chatter, chatter to no end for an hour or more, when the idea occurred to me to tell her of an experiment I had tried by which my voice came more easily.
