Demosthenes – [Gullibility]

No man who is not willing to help himself has any right to apply to his friends, or to the gods.

Nothing is easier than self-deceit. For what each man wishes, that he also believes to be true.
Demosthenes – [Belief]

Small opportunities are often the beginning of great enterprises.
Demosthenes – [Opportunity]

The readiest and surest way to get rid of censure, is to correct ourselves.
Demosthenes – [Censure]

To remind a man of the good turns you have done him is very much like a reproach.
Demosthenes – [Gratitude]

What we wish, that we readily believe.
Demosthenes – [Faith]

You cannot have a proud and chivalrous spirit if your conduct is mean and paltry; for whatever a man's actions are, such must be his spirit.
