Robert Fanney said this quote
“ Writers shouldn't fear criticism. Instead, they should fear silence. Criticism is healthy. It gets people thinking about your work and, even better, it gets them talking and arguing. But as for silence -- it is the greatest killer of writers. So if you hate a book and want to hurt it -- don't talk about it. And if you hate my books -- please, for God's sake, shout it from the hills! ”
