QUOTE : On a far-wandering walk a thousand useful and usable thoughts occur to me, while shut in at home, I would lamentably wither and dry up. Walking is for me not only healthy, and lovely, it is also of service - not only lovely, but also useful. A walk advances me professionally, and provides me at the same time with amusement and joy; it conforts, delights and refreshes me, is a pleasure for me, but also has the peculiarity that it spurs me on and allures me to further creation, since it offers me as material numerous more or less significant objectivities upon which I can later work industriously at home. Every walk is filled with phenomena valuable to see and feel.
