Hi will-be-apostate,
Just yesterday I was speaking my own very similar thoughts as you did in your OP, as a culmination of trying to carve out a sustainable path in this world with my life over the last two decades. I, like millions of other JWs who will eventually die, was nicely catapulted into the world right out of high school into a system that was supposed to 'end' before I had to grow up in this world and need to make a living for myself.
I've had both abudnant and fallow seasons in my work and in making a 'mark', so to speak, but I can't seem to bypass the sentiments of Eccelesiastics and feeling like it's all a striving after the wind.
Incidently, I was triggered by seeing the bones of my toes under my skin and muscles as I flexed and stretched my bare feet while sitting on the sofa drinking my coffee before going to work. That made me think of my skeletal system, and the 'bones' that we all end up being after we've come and gone our short time on this earth.
That reminded me of a documentary about Pompeii I saw, where the skeletal remains of a very wealthy (royal?) family were found lying with many gold bands and bracelets and other jewelry still around their dead bones, lying next to their "servants" who had nothing of the sort, but arrived just in time for the same fate as their masters because of the volcano lava.
Death, the great equilizer, which none of us gets to bypass. That's one of the ways I've been able to come to terms with being just one of the 7 billion. Life does seem to be like one big act in a play, with all its varied actors, doesn't it?
And yet, being here right now in this connection with others seems miraculous.
