If you take no action, you will likely get no results. Always follow-up by phone. You can do anything if you have enthusiasm. Enthusiasm is the yeast that makes your hopes rise to the stars. Enthusiasm is the spark in your eye, the swing in your gait, the grip of your hand, the irresistible surge of your will and your energy to execute you ideas.
Enthusiasts are fighters, they have fortitude, they have staying qualities.
With it, there is accomplishment. Without it, there are only alibis. The major quest in life is not what you are getting, but what you are becoming.
