Most problems with creative writing these days stem from deadlines. Writer gets commission to write something. Publisher tells writer to finish current chapter by the end of the month. Writer goes to lots of parties and forgets about deadline.
Publisher gets irritable when first deadline passes.
Publisher gets angry and sets another deadline. Writer tries to do some writing, and misses said deadline. Writer eventually finishes book. Publisher is happy, and pays writer copious amounts of money. Writer is mobbed by scores of marauding fans armed to the teeth with autograph books.
