The author Scott Raab offers some insight and advice:
“I think the fundamental force behind writing is passion. The writers I know are insane. They don’t know how NOT to write about stuff. It’s like pro athletes often say about their sport: They’d play for free.
“Same with reading. Anybody who has no time to read isn’t a writer. All the work necessary to learn how to write boils down to reading and writing. This is not subtle or nuanced advice, obviously. I stress it here because of how often I talk to people who seem to think there’s a shortcut. I know no shortcuts.”
