In these days of keen competition and wonderful activity it is
necessary for the business man to have enthusiasm. If he lacks in this,
his business will be at a stand-still, while his enthusiastic
competitor goes forward.
Enthusiasm should not be carried to an extreme any more than any other
good thing should be carried to an extreme, but at that it is better to
be over-enthusiastic than not enthusiastic enough. No one can be truly
enthusiastic who does not believe in his business. Enthusiasm is a form
of advertising. It shows the people you deal with that there is
something going on and that you believe in your own medicine.
