How do I find time to write?

Dear Literary Ladies,
I would dearly love to call myself a professional writer, but I’m so easily distracted. After the kids go to school, it’s off to work, the gym, and endless errands. On weekends, I entertain family or visit with friends. In the midst of all this, I can’t seem to find time to write. How can I fit everything in?

To be a professional writer one must be prepared to give up almost everything except living. Amateur writers are not included in this rule (I loathe loud-talking amateurs of any walk of life. An amateur is an apprentice and should conduct himself as such, keeping his mouth shut and learning his craft). The first lesson to be learned by a writer is to be able to say, “Thanks so much. I’d love to, but I can’t. I’m working.”

—Edna Ferber (A Kind of Magic, 1963)
