Addiction: When the pleasure of anticipation outweighs the logical value of the object you are anticipating, thus making you pursue it even though further consumption of that object will get you sick, fat, broke, or otherwise brain dead. Thus, looking forward to one beer (or bag of chips, cigarette, spin on a roulette wheel, etc.) is not addiction, but looking forward to a tenth beer is; conquering Italy (particularly if you are Napoleon) is not an addiction, but conquering Russia is; playing a video game for an hour is not addiction, but continuously playing it for twelve hours is; and looking at one picture of Britney Spears is not an addiction, but relentlessly searching for all her pictures is. (Also see dopamine)
