The Larks Song

"This world is eventually going to end. I know it, you know it. At one point or another, life as we know it will simply cease to exist. Life at all will cease to exist.
Whether that be from some astrological phenomenon, nuclear warfare, climate change, or divine intervention, it's going to happen. Most likely, after everyone on earth, currently, have already died.
That's the other end. The end of life. We spend so much of our lives fearing it, that when it comes, that's all we've done. All we've thought about.
We've spent our entire lives trying to stop their own end. And then it comes, and that's it.
The end.
But what if someone where to change that. Try to do their best for the future, sure, but not for their future. For the future of others. Trying to inhibit the first end, rather than the second.
Well then they're hailed as a hero. A stressed out, probably at least slightly unhappy hero. But a hero just the same.
So, by all accounts, no one can be truly happy. You're either worried about your own demise, or the demise of everyone else in the future.
So you just have to get as close as you can."
