I don't believe in "writer's block." Although of course there are days when one's creativity is in full swing and others when it seems to disappear, when the writing doesn't go well for whatever reason.
I like to think of those periods as a pause in creativity. No block. Nothing I can't change when I'm good and ready, just a slight pause.
There's plenty to do when it happens, things that are part of a writer's work. Update the website. Read articles about the publishing business. Stay involved on social media. Organize files. Read books!
One nice thing about a creative pause is feeling like a normal person instead of a slave to whatever book is after you, pushing itself to get written. You can relax and enjoy life instead of agonizing over every "wasted" moment not spent writing.
Writer's block has negative connotations. The creative pause is rather nice. It can be a welcome respite from the intense productivity that comes when creativity is in its fullness with its prodding, pushing, unrelentless attack on your time, talents and energy.
No need to dread the creative pause, is what I tell myself. Welcome and embrace it, enjoy it, make the most of it. Like all good things, it will come to an end in its own good time.
