I’ve actually done this when I’ve opened my journal.
Pick up your pen; open your notebook or journal and…
…Blah Blah Blah…
…Have nothing to write so writing I have nothing to write until my pen finds something to write from inside my head…
Yes, our pens bleed the ideas out of us because we are driven to write even if it’s only: Blah Blah Blah, nothing to write.
Try it, who will know?
