From your point of view.

It appears to me that problems can always be thought of as a lack of light illuminating your path. Problems shroud your perceptions in darkness, and when you see a flicker, an afterimage of light, you trudge in the direction you thought you saw it. For all you can see you may as well be in a tunnel. You may as well be walking a tightrope. You may as well be walking toward a cliff.
