Were you a Spinal Tap fan? There's a line (can't find a clip) where they're standing at Elvis's grave.

I've been in a similar mode to you for a while, due to similar reasons. The main takeaway through it all was to try to force myself to acknowledge that the same fate is coming for me, just not yet. And to ask whether I'm living in a way that, when it arrives, I'll be ready, or ready as I can realistically be. I have typically not enjoyed the answer.

It's funny, bitcoiners talk about "fiat mindset" all the time, but my strong suspicion is that we're just as sick with it as anyone, and even fat btc bags obscure the truth that we're finite, that everything precious will be taken, and that it requires both strength and foresight to live in acknowledgement of that truth, to build and "invest" in life and in ourselves in a way that gives a good accounting eventually.

The method for doing so is as old as time. There are probably other methods as well. None of them have got easier.
