It's our enthusiasm that make us what we are
For every sale you miss you're too enthusiastic, you will miss a hundred because you're not enthusiastic enough.
I studied the lives of great men and famous women, and I found that the men and women who got to the top were those who did the jobs they had in hand, with everything they had of energy and enthusiasm.
You can do anything if you have enthusiasm. Enthusiasm is the yeast that makes your hopes rise to the stars. With it, there is accomplishment. Without it there are only alibis.
Every man is enthusiastic at times. One man has enthusiasm for thirty minutes - another for thirty days, but it is the man who has it for thirty years who makes a success of his life.
Edward B. Butler
Those who are fired with an enthusiastic idea and who allow it to take hold and dominate their thoughts find that new worlds open for them. As long as enthusiasm holds out, so will new opportunities.
Norman Vincent Peale
