Here's a nice Saturday morning routine you might want to start.
Get up and have a little breakfast. Pour a cup of your favorite morning beverage and head out to your front stoop with the broom.
Shake the doormat, pick up any trash about the place, and sweep the dirt up.
If you live in an apartment building, this could just be sweeping a bit around your door and the path you take to the stairs or elevator, but I recommend even in that case going on down to the street door and sweeping the sidewalk. It doesn't take long, it makes a place you see every day nicer, and it gives you a chance to say hello to your neighbors.
Urban and suburban lives are often far more isolated than is healthy, either for the people who live that way or the neighborhood as a whole. Get to know at least the faces and better yet, some names.
