Some words of wisdom from those cleverer than us:
“This above all: to thine own self be true”. – Hamlet (Act I, Scene III).
The visionary lies to himself, the liar only to others.
Friedrich Nietzsche
All men are frauds. The only difference between them is that some admit it.
I myself deny it.
H. L. Mencken
A lie told often enough becomes the truth.
Any fool can tell the truth, but it requires a man of some sense to know how to lie well.
