{No one is allowed to start worrying: it's a thought-experiment, not an intention.} :-)

What would you do if you found out that soon, say tomorrow, you'd be dead?

Oh, I know that, realistically, most people who were put in that situation would spend a fair amount of time grieving, but I would want to point out that that time would not extend the deadline. I would rather spend time with my loved ones instead of saying goodbye to them.

And hopefully too, it would put a glaring spotlight on reality: denial and other forms of lying to oneself would just waste time, as well. And there's no point in thinking about "bucket lists"; you probably won't have time to arrange any fancy activities like going to see the Pyramids before you die. On the opposite side, though, you're also not going to be able to pack a lifetime's work into that day, just so that your kids can inherit your riches.

So, what goals remain important to do, for that one day?

You could hold your kids' hands. I'm pretty sure they can make their own fortunes.

You could marvel at the structure in a flower, or the sunlight flashing through the trees, or the raindrops pouring from the sky. Sure, none of that will help once you're dead, but they're the sort of things that do a soul good while it's alive.

You could talk to someone about what matters to you, give them a memory of you to hold on to, show them how much you love them.

Some things matter, and some things don't.

Don't get caught up in the ones that don't.
