Gold worthy advice

If you are in a tunnel and you want to get out of it you must be focused on the light at the end of that tunnel.

If you want to get out of the tunnel you must be focused on the light at the end of the tunnel and not on the darkness.

If you find yourself in a tunnel where you can't see the light you have two choices, either to turn back and go where you came from and where there was light, or you can continue digging that tunnel until you step out into the light.

But in both situations you must be focused on getting out of the tunnel! Into the light!

If you want to get out of the tunnel you must be focused on the light at the end of the tunnel and not on the darkness that surrounds you.

That is the point of the whole story.
