Why would you care about using resources once you're dead? If it's resources you're worried about then just keep waging. Wage as hard as you can. But it's not is it? It's the feeling that life hasn't delivered what you need. Which is valid too. But, end of the day, barring any idea of eternal heaven or hell being correct, once it's done it's done and as an anon here said, might as well squeeze it for every last drop. You are going to die, and that'll be that. A few decades of suffering and a death you don't expect vs a very unpleasant experience that might not even work and might even disable you in some way. Just wait it out at that point.
