Should the world end tomorrow, today will have been my last day to live. But what should my thoughts matter against the multitude? There were millennia before I existed, there shall be millennia after I exist, and what bit of information I contribute to the whole shall only be conserved according to the laws that govern it.
Against the multitude, I am nothing.
Yet in this instant I am something–and so I have been for eternity.
And so I will be. I always will be.
