Strangers in a Strange Land

Robert A. Heinlein
I think that science fiction, even the corniest of it, even the most outlandish of it, no matter how badly it's written, has a distinct therapeutic value because all of it has as its primary postulate that the world does change.

David McCullough
One night, he was at a party with Harry Sinclair Drago, who had written more than 100 Westerns. McCullough got up the courage to approach him and ask him how he did it, and Drago said he wrote four pages a day, no matter what. McCullough said, "It was the best advice an aspiring writer could be given."
