As a writer, I have the most demanding boss in the world. Myself. And I recently discovered the secret to busting creative block.
I found a refreshing enthusiasm for accomplishing hard things by spending a few rigorous hours practicing the piano--a few rigorous hours for a few days. And I also took time to make S'mores over a bonfire, watch the sunset, and have a "Just Dance" competition with over twenty people in my basement. When I returned to my writing, I found two more ideas for picture book manuscripts waiting in the now relaxed creative corners of my brain. I found the solutions to the problems I was having with a work in progress and I prepared three manuscripts for submission.
The ideas and the answers are in there. Sometimes, a creative distraction is needed to allow them to break free. And, in case you were wondering about that piano piece--"Dancing on the Berlin Wall" by David Lanz.
