Don't worry about it. Nobody lives for anything. You're born, you live and you die. All accomplishments, all money, all events are instantaneous. You've been and you're dead. And you have nothing and you're gone, just like you never existed.
How to spend this microscopic interval, when you are, is everyone's business, and it is absolutely indifferent how it will be. All lyrics, consciences, morals, meanings and other bullshit are for the living, so that they don't get so obsessed about their meaninglessness and insignificance. Many people need something to believe in, some invented religions for the sake of it, not to be afraid of death and to fill their lives with something. But in fact everything is empty, does the life of a flea or a cell in an organism, even if it is very important and pompous, make sense. Don't worry, while you live, live, when you die, well, you die and that's it. Nobody gives a fuck, even those who don't give a fuck, don't give a fuck, at least because there are no options anyway. The universe doesn't give a fuck, the world doesn't give a fuck, evolution doesn't give a fuck, so the fact that you don't give a fuck is normal.
