I kept coming back to this route for respite from my work and for my work too, because thinking is generally thought of as doing nothing in a production-oriented culture, and thinking is hard to do. It’s best done by disguising it as doing something, and the something closest to doing nothing is walking.

Reminds me of Thoreau:
"I think that I cannot preserve my health and spirits unless I spend four hours a day at least — and it is commonly more than that — sauntering through the woods and over the hills and fields absoutely free from all wordly engagements."
