Loafing is the most productive part of a writer's life.
James Norman Hall

All writers are vain, selfish and lazy, and at the very bottom of their motives lies a mystery. Writing a book is a long, exhausting struggle, like a long bout of some painful illness. One would never undertake such a thing if one were not driven by some demon whom one can neither resist nor understand.
George Orwell

Better to write for yourself and have no public, than to write for the public and have no self.
Cyril Connely
