In the end, nothing works out permanently.
Even the biggest, most robust organisations pass and fade away over time. Life as we know it keeps on changing, despite our best efforts to stop that happening. And eventually, all of us die, leaving everything we’d accumulated and created behind us. Before long, all of that disappears too.
So whatever you’re working on now, whatever glorious future plans and hopes you’re working towards, it would be worth checking that what you’re doing is also worth it for its own sake, regardless of how it turns out.
Because in the end, that it mattered at the time might be all that’s left.
