You stand up and you start walking.
You don't know where you're going.
You're just walking.
Then you run into a wall.
The wall is made of straw.
Well you realize you can just blow it down.
So you do that.
Then you run into a wall made of wood.
So you break through it with your foot.
Then you run into a wall made of stone.
So you pick up a pick axe and start beating at it.
Then you run into a wall made of an unbreakable force.
You have no idea how to get around it.
Once you see it you keep trying to figure out how to get through it.
But you cant figure it out.
But you cant get your mind off of it.
So you sit there until one day you look back,
and see all the progress you've made,
and you decide that you've done enough.
