A man can succeed at almost anything for which he has unlimited enthusiasm.
Harry F. Banks
A salesman minus enthusiasm is just a clerk.
A word is dead when it is said, some say. I say it just begins to live that day.
Act enthusiastic and you become enthusiastic.
Be enthusiastic as a leader. You can't light a fire with a wet match!
Catch on fire with enthusiasm and people will come from miles to watch your burn.
Thomas J. Peters
Celebrate what you want to see more of.
Francois Pierre Guillaume Guizot
Do not be afraid of enthusiasm. You need it. You can do nothing effectively without it.
Vincent Van Gogh
Do not quench your inspiration and your imagination; do not become the slave of your model.
