rush and throb

Yes, I get dry spells. Sometimes I can't turn out a thing for three months. When one of those spells comes on I quit trying to work and go out and see something of life. You can't write a story that's got any life in it by sitting at a writing table and thinking. You've got to get out into the streets, into the crowds, talk with people, and feel the rush and throb of real life—that's the stimulant for a story writer.
