Ah, the meaninglessness of it all. I suffered with this for quite some time.
But if it's all essentially meaningless, then it means nothing that it's meaningless. It doesn't "mean" stop doing things, as I did. It doesn't "mean" give up, as I did.
It doesn't mean a damn thing, so the influence of "meaning" is damn near zero.
I stopped wasting time up in my head. Then I started living... a bit.
