"when you want something so desperately, you shake with the need for it. you tell yourself that you don't need more than one sip, because it's just the taste you crave, and once it's on your tongue you will be able to make it last alifetime. you dream of it at night. you see a thousand mile-high obstacles between where you stand and what you want, and you convince yourself you have the power to hurdle them. you tell yourself this even when, leaping the first block, you wind up bruised and bloodied and flattened."
