The Slow Burn

Keep working, gotta find the end.
No stopping till you make it.
Keep working, you’re almost there.
You can’t see the light just yet.
Keep working, it will come soon.
There’s a wall.
Keep working, it can’t be long now.
No way through, gotta go around.
Keep working, it can’t go on forever.
You dug a nice grave.
Keep working, it won’t fill itself.
