I see nothing for you on this earth but that field which I once christened Briars; go out upon that, build yourself a hut, and there begin the grand process of devouring yourself alive. I see no alternative, no other hope for you. – William Ellery Channing

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, absolutely free from all worldly engagements. – Henry David Thoreau
