I was told an interesting tale today, which is as follows:
'A small Hungarian detachment was on military manoeuvres in the Alps. The lieutenant sent a reconnaissance unit out into the icy wilderness just as it began to snow. It snowed for two days and the unit did not return. The lieutenant feared that he had dispatched his people to their deaths, but the third day they returned. The lieutenant asked them how they had made their way back? Yes, they said, we considered ourselves lost and gave up, waiting for the end. Then one of us found a map in his pocket. That gave us hope, we pitched camp, waited for the storm to pass and then took our bearings, and here we are. The lieutenant looked at the map and found to his astonishment, that is was a map of the Pyrenees, not of the Alps at all.' (Albert Szent-Gyorgi)
So, if you're completely lost, any map is better than none at all. It can provide a reference point, a place to start from, the hope that things can change, all of which may become secondary once an activity gets underway.
