Most people need to know that they have been heard. Listen to their body, their eyes, to the colors they are wearing. If you really want to hear someone, open your heart and listen to their soul.
There is no art to wandering. If I have a destination, a plan -- and objective -- I've lost the ability to find serendipity... I search for the Holy Grail of particularity and miss the chalice freely offered, filled full and overwhelming.
