Walls

Imagine a wall with a trap door hidden in it.  You feel around blindly.  You inspect every crack and hole.  You step back and look for faint patterns.  You look high.  You look low.  You jump.  You crawl.

You get tired.
You lean against the wall and stop searching.
The door opens behind you, under your weight.

Your journey has brought you here.  To this particular wall.  Feel, inspect, step back, attempt, fail, lean on it for support.  You are learning everything you need to know to survive on the other side.

When the door opens, walk through it.
One step at a time.
