From Editor to Author: The Letters of Maxwell Perkins, edited by John Hall Wheelock
"Learn about writing from reading. That is the right way to do it. But then it can only be done by those who have eyes and ears, by seeing and listening. Very few great writers had that formal education, and many of them never mastered spelling or grammar. They got their vocabulary by reading and hearing."
