If your nihilism doesn't make you happy, you're doing it wrong. The absence of meaning should be a liberating factor, not a limiting one. It's actually dope as fuck that there's no greater purpose to your life, you can never fail as a person when there's no standard you feel you have to meet.
basically life is minecraft: there's no goal, we have to give ourselves reasons to live, and we can make those reasons precisely whatever the fuck we want, and that's what makes it so fucking brilliant.
It's like the people who crow on about how we're living in a simulation. Okay, so what? I still have to live my life as if I'm not living in a simulation. I still can see that what I do has effects that ripple out starting with those closest to me.
I think the fucked up part is not the not having meaning, its the, if there is no meaning why the fuck do we still have a society based on perpetual human suffering for profit. Lets make something better.
