Light at the end of the tunnel

At times in our adventure, we peer down a dark passage, wondering if we should enter.  Often wonderful things are at the other end.  I recall entering a passageway in Amsterdam, really not sure if I should.  It was dark, there were druggies around, but the map indicated it was the way to get to the main square, and it was.  A minute later I was in the main square, safe a sound.  I was so glad I didn't let fear of the darkness stop me from entering.
