in Thoreau’s Journal:

Winter has come unnoticed by me, I have been so busy writing. This is the life most lead in respect to Nature. How different from my habitual one! It is hasty, coarse, and trivial, as if you were a spindle in a factory. The other is leisurely, fine, and glorious, like a flower. In the first case you are merely getting your living; in the second you live as you go along. You travel only on roads of the proper grade without jar or running off the track, and sweep round the hills by beautiful curves.
