One way to salve the wounds of rejection by publishers or literary agents is to read rejection lessons received by other, far greater writers. There are numerous collections of these, but I recently stumbled across a small, new compendium of rejection letters on the web site Flavorwire.
It includes rejection letters received by Kerouac, Plath, Gertrude Stein and others, but here is my favorite. The Left Hand of Darkness won the 1969 Nebula Award and the 1970 Hugo award, and established LeGuin as one of the most respected sci-fi/fantasy writers of her generation.
(Of course, what we don’t know is what kind of manuscript LeGuin had turned in! Maybe it was “hopelessly bogged down” and she rewrote significantly before it was eventually published.
Then again, maybe not.)
