Talk incessantly. Dwell on temporal affairs. Ask friends for advice; ignore it. Air out perceived problems constantly. Respond defensively. Never take criticism at face value. Write off whoever won't humor you. Accuse others of misunderstanding you. Build your lifestyle on whims. Presume entitlement to *** for "being nice". Choose an inappropriate diet for your body. Avoid personal responsibility. Refuse to own your failures and errors. Justify behaviors that create conflict. Rationalize unfruitful thought and action at all cost. Dismiss what contradicts your prejudices. Compare yourself to Jesus. Insist on your specialness. Insist that others acknowledge it. Don't communicate your expectations. Blame others for your bad choices. Fish for compliments. Use sentiment to ply others. Use sentiment to ply yourself.
Subject anyone to yourself while the above applies to you.
It's called a "toxic person", ladies and gentlemen.
