Droplets glide down a branch easily and quickly. They meet along the way and form into a heavy ball of water before falling to the ground. We humans love travelling, too. And collect new sights and sounds and tastes. For a while they energize us and inspire us. When the excitement is over, we look for the next adventure. Lucky are those who eventually realize that the most enriching journey is not in the next town or country or island – but inside us. The Sioux say it best: the longest journey we’ll ever make is from our heads to our hearts.
