man lies to himself a lot.

Above all, do not lie to yourself. A man who lies to himself and listens to his own lie comes to a point where he does not discern any truth either in himself or anywhere around him, and thus falls into disrespect towards himself and others. Not respecting anyone, he ceases to love, and having no love, he gives himself up to passions and coarse pleasures in order to occupy and amuse himself, and in his vices reaches complete beastiality, and it all comes from lying continually to others and himself. A man who lies to himself is often the first to take offense. it sometimes feels very good to take offense, doesn't it? And surely he knows that no one has offended him, and that he himself has invented the offense and told lies just for the beauty of it, that he has exaggerated for the sake of effect, that he has picked up on a word and made a mountain out of a pea — he knows all of that, and still he is the first to take offense, he likes feeling offended, it gives him great pleasure, and thus he reaches the point of real hostility...

Often, men who would never think of lying in the workplace lie constantly in intimate relationships. This seems to be especially the case for heterosexual men who see women as gullible.

Men under stress are fools, and fool themselves.

Men lie to get laid, women lie about orgasms, and hermaphrodites lie to themselves.

When a man really tells the truth, the first truth he tells is that he himself is a liar.

We lie the loudest when we lie to ourselves.

…we all lie to ourselves; we tell our own selves more lies than we ever do other people.

Do not expect people to tell you the truth because they also lie to themselves.

The worst lies are the ones we tell ourselves. we live in denial of what we do, even what we think. We do this because we are afraid. We fear we will not find love, and when we find it we fear we will lose it. We fear that if we do not have love we will be unhappy.

If it is necessary sometimes to lie to others, it is always despicable to lie to oneself.

The greatest deception which men incur proceeds from their opinions.

And yet they lie all the time, both when they wish to lie and when they wish to speak the truth. They lie all the time, both to themselves and to others.

The most common sort of lie is that by which a man deceives himself: the deception of others is a relatively rare offense.
