Above all, don't lie to yourself. The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others.
A man who lies to himself, and believes his own lies, becomes unable to recognize truth, either in himself or in anyone else, and he ends up losing respect for himself and for others. When he has no respect for anyone, he can no longer love, and in him, he yields to his impulses, indulges in the lowest form of pleasure, and behaves in the end like an animal in satisfying his vices.
