Ralph Waldo EmersonWhen you have worn out yourshoes, the strength of the shoe leather has passed into the fiber ofyour body. I measure your health by the number of shoes and hats andclothes you have worn out.
Ralph Waldo EmersonBut it is a cold, lifeless business when you go to the shops to buy something, which does not represent your life and talent, but a goldsmith's.
