To myself, regarding death:
You are going to die. You may not like to think about it, but it’s going to happen. Maybe tomorrow. Maybe in 50 years. Who can say? That’s the bit you can’t know (thankfully). But you do know where you’re going to end up sooner or later. You do realize how short 100 years are, don’t you? You do realize how many people don’t even make it that far.
You are going to die. Everything you loved and feared, all your petty remonstrances and trivial irritations will be dust. Time will bury everything, wonderful and hateful, lies and truth. And in a few short years after your death, it will be as though you never existed. This alone should make you cling to every passing moment—no matter how monotonous or unpleasant—but you’re as dumb as a post, forgetful, myopic. You don’t understand a thing.
You are going to die. Yet you waste your days worrying about the opinions of others. After you die, people will actively try to forget you—and will largely succeed—because you will remind them of their own mortality. Even now while you are still alive, the only time people want to consider you or something connected to you is when it somehow makes them feel better about themselves. How different will it be when you’re nothing but rotting meat? At best, the thought of you will inspire grief and a sense of loss—at worst, revulsion, resentment, aversion. No one will want to care. Eventually people won’t take the time to speak your name—the word which used to stand for you but which now stands for nothing.
You are going to die. Still, you waste time planning and striving as if worry and toil could add days to your life. There is no life but the one you are living. You don’t get more days. You only get fewer. And every moment spent enslaved to a meaningless job, a tyrant, an empty social obligation, an imaginary god, vain status seeking, or the quest for symbols of wealth / worth is an act of fraud against yourself. The great herd trots into the slaughterhouse, worrying about tomorrow’s breakfast—never thinking that it will, in fact, be them.
You are going to die. And until you realize it in your heart of hearts—until you embrace the specter of death and kiss its grinning skull and know and accept and understand that your time is painfully, stupidly short—you will not have begun to live. Time will destroy everything but death. There is no morality. There are no obligations. There are no commandments or requirements beyond this one realization.
