Before the first step you draw the map.
You don't want to get lost.
So you mark the detours. The dead ends.
Add corridors for the trouble you haven't met yet.
Somewhere it stops being a map.
Starts looking more like a maze.
Then the actual work arrives.
Simpler than anything on the map.
One thing to do. Then another.
You're through it without the map.
Fold it. Pocket it.
The elaborate parts never used.
You didn't get lost.
Just took a long time to leave.
