Paul David Chambers
I tend not to get writer's block per se, but do have issues with focussing at times. Once I get to focus, it tends to flow. If I'm feeling unproductive, I know there's no point even trying, as you can't force it. When that happens, I take a walk on my own in the countrywide, listening to music; and do my 'mental filing' as I like to think of it. Stop forcing the thoughts and allow them to come of their own free will.
