Light

There's always light at the end of the tunnel.

The question is, where is the end of the tunnel? Which direction is it? East? North?

Some people with a clear mind steadily find their directions and slowly move to the direction of the light.

However apparently not all of us know how to get there, merely hoping the light is there, because we are told so or we imagine so.

So we fumble blindly in the dark, hoping it's going to be the end and we will see the light soon. How smart.
