"There are days when the technique of an aimless stroll -- without timetable or destination -- works like a charm, flushing out pictures from the non-stop urban spectacle." - Robert Doisneau, photographer

I wouldn't presume to put myself in a class with Monsieur Doisneau, but this quote certainly sums up a truth I hold to.  It is delightful to take in the city as a whole, narrow your focus until a single, concentrated moment fits inside your viewfinder, and then snap a photo into being.
