Words aren't cheap by Katherine Paterson

Words are humanity's greatest natural resource, but most of us have trouble figuring out how to put them together. Words aren't cheap. They are very precious. They are like water, which gives life and growth and refreshment, but because it has always been abundant, we treat it cheaply. We waste it; we pollute it, and doctor it. Later we blame the quality of the water because we have misused it.
