Here’s an interesting quote from William Walker Atkinson:

“The enthusiastic man naturally tends toward the optimistic frame of mind, and by doing so he diffuses an atmosphere of confident, cheerful expectation around him which tends to inspire confidence in others, and which aids him in his endeavors.

He surrounds himself with a mental aura of success – he vibrates success – and those into whose presence he comes, unconsciously take on his vibrations. Enthusiasm is very contagious, and one filled with the right quality, kind and degree of it unconscious communicates his interest, earnestness and expectations to others. Enthusiasm plays an important part in that which is called Personal Magnetism. It is a live, warm, vital mental quality, and it quickens the pulse of the one using it, and those who are affected by it. It is different from the cold-blooded indifference that one meets with so often in business, and which causes many a sale to be lost, and many a good thing to be “turned down”.

The man who lacks Enthusiasm is robbed of more than half his force of Personal Influence. No matter how good his arguments may be – no matter how meritorious his proposition may be – unless he possess the warm vital quality of Enthusiasm, his efforts are largely wasted, and his results impaired.

Think over the salesmen who have approached you and remember how some of them produced the chilling effect of a damp cellar upon you, while others caused you to sit up and take notice in spite of yourself by reason of their earnest interest and enthusiasm. Analyze the impression produced upon you by the different people with whom you have come in contact, and see how great an influence Enthusiasm exerts. And then remember the effect it produces upon yourself, when you feel it.

Enthusiasm is Mental Steam – remember that.”

This is nothing new that the students of Personal Magnetism already know very well. Enthusiasm is magnetic, while monotony kills the magnetism. It’s always important to remember this important lesson.
