Philip José Farmer on Writing
“Imagination is like a muscle. I found out that the more I wrote, the bigger it got.”
“Despite my vast interest in other universes and new ideas and space, travel and time travel, which by the way I think is impossible, the basic thing is human character, which is the main thing of most writers.”
