I wonder how it was possible to walk for an hour through the woods and see nothing of note. I who cannot see find hundreds of things: the delicate symmetry of a leaf, the smooth skin of a silver birch, the rough, shaggy bark of a pine. I who am blind can give one hint to those who see: use your eyes as if tomorrow you will have been stricken blind. Hear the music of voices, the songs of a bird, the mighty strains of an orchestra as if you would be stricken deaf tomorrow. Touch each object as if tomorrow you could never taste or smell again. Make the most of every sense. Glory in all the facets and pleasures and beauty which the world reveals to you.
– Hellen Keller
