here are some tips on how to be less polite (in no particular order):

• Set yourself a goal
• Find yourself an arch enemy that opposes your goal
• Be willing to sacrifice anything to defeat your archenemy
• Steal a gun from your arch enemy
• Forget about or surpress unimportant emotions like empathy
• Ascend to a higher plane of existence
• Never give up under any circumstance (Borrow willpower from the future if necessary)
• Be insanely patient
• Smile at the misfortune of others
• Be sarcastic always, never show your real emotions
