What this power is I cannot say all I know is that it exists and it becomes available only when a man is in that state of mind in which he knows exactly what he wants and is fully determined not to quit until he finds it. – Alexander Graham Bell

No man deserves to be praised for his goodness, who has it not in his power to be wicked. Goodness without that power is generally nothing more than sloth, or an impotence of will. – Francois de La Rochefoucauld
