Goethe:

Treat a man as he is, he will remain so. Treat a man the way he can be and ought to be, and he will become as he can be and should be."

Henry David Thoreau:

Our circumstances answer to our expectations and the demand of our natures.

Mario Andretti (Italian born American Race driver. b.1940)

Desire is the key to motivation, but it's determination and commitment to an unrelenting pursuit of your goal - a commitment to excellence - that will enable you to attain the success you seek.”

Sonian1 Joss Whedon

 “Passion, it lies in all of us, sleeping... waiting... and though unwanted... unbidden... it will stir... open its jaws and howl. It speaks to us... guides us... passion rules us all, and we obey. What other choice do we have? Passion is the source of our finest moments. The joy of love... the clarity of hatred... and the ecstasy of grief. It hurts sometimes more than we can bear. If we could live without passion maybe we'd know some kind of peace... but we would be hollow... Empty rooms shuttered and dank. Without passion we'd be truly dead.”
