If nothing happens after we die, what's the point of it all?
We spend our days bound by endless obligations. Yet, even with loneliness, failed relationships, and soul-draining work, people still manage to catch a glimpse of happiness. Why?
There's no meaning, no purpose. We're random life on a random planet. Try to have a happy life and try not to inhibit the happiness of others. That's it.
But you have to actually believe it. So the trick is to find your purpose, as much as it is to make it up. There's something in you that wants to come out... or maybe not!
