Walking [with Biographical Introduction]

by Henry David Thoreau

The thought of some work will run in my head and I am not where my body is—I am out of my senses. In my walks I would fain return to my senses. What business have I in the woods, if I am thinking of something out of the woods? I suspect myself, and cannot help a shudder when I find myself so implicated even in what are called good works—for this may sometimes happen.
