“I who am blind can give one hint to those who see - one admonition to those who would make full use of the gift of sight: Use your eyes as if tomorrow you would be stricken blind. And the same method can be applied to other senses. Hear the music of voices, the song of a bird, the mighty strains of an orchestra, as if you would be stricken deaf to-morrow. Touch each object you want to touch as if tomorrow your tactile sense would fail. Smell the perfume of flowers, taste with relish each morsel, as if tomorrow you could never smell and taste again. Make the most of every sense; glory in all the facets of pleasure and beauty which the world reveals to you through the several means of contact which Nature provides.”

Three Days to See (1933)
