The best journeys, it seems to me, are the unplanned ones, taken on the spur of the moment, reliant on the benifecence of serendipity. I understand why not everyone who travels would agree with this. For serendipity to work, one must believe in it. Listen for its song. Follow its voice when it calls. One cannot do this if plans are laid down like concrete foundations. Planning must be fluid, flow like a rivulet on a sandy beach, as easily diverted as the whim of a child with a stick.
