Some motivation to begin your week:
"They say writing is lonely work. But that's an exaggeration. Even alone at their desks, writers entertain visitors: characters of a novel, famous and not so famous figures from the past. On good days, all these come to the table. On bad days, however, only unwelcome visitors appear: the specter of your third grade teacher who despaired of your penmanship…"
— Allegra Goodman
As a writer, you will have good days and bad days. The challenge is learning to go with the flow and keep writing. All writers ask questions about their calling. Has someone else written this? Did they do a better job? Am I crazy to think I can handle this? These are the "unwelcome visitors." Set these aside voices and continue to put words on the paper every day.
Have a wonderful week!
