"Be where you are."
Wherever you are, note the architecture,  nature of business, offices or houses, the trees, flowers,  and other plants, rocks, sand  and soil, water, signs of weather, sounds and smells,  machines and technology, sidewalk or trail, artwork and litter, character of the neighborhood, dogs, horses, cats or other animals, and most of all the variety of people you might meet  or greet if you're not alone.
