1. Thou shalt not listen to anyone, for they are all wrong and thou art always right. 2. Thou shalt not be punctual, for punctuality is for suckers. 3. Thou shalt not return phone calls or texts, for they shall not bother thee with their inane chatter. 4. Thou shalt not make eye contact, for it makes others uncomfortable. 5. Thou shalt not apologize, for it doth weaken thy resolve. 6. Thou shalt not be kind, for kindness is overrated. 7. Thou shalt always, always, ALWAYS be correct, for thou art never, ever wrong.
And remember, being a jerk is not just a skill, it's an art.
