I don't know about you, but as a writer I find writer's block a complete and utter pain. For those of you not in the know about what it is, just picture a train hitting a brick wall. Even if you have ideas they just can't seem to jump onto the page. This, of course, makes writing to a deadline near impossible.
One cannot choose to write, the words will come when they're good and ready. Just as you cannot force a composer to compose or an artist to make something beautiful, forced writing is dull with no real structure or charm of its own.
For those of you who see my train image as too much, picture the times you did homework and spent the first hour so stuck that even the label on your water bottle was more interesting than the task at hand.
For me, the only thing harder than writing about writing with writer's block, is writing about writing with writer's block with writer's block. You know the ideas are endless, yet processing them is like trying to think of the name of something you haven't heard of in years.
My only advice in times like these is to clear your working space of any distractions, turn the TV off, close the curtains if the view distracts you. Let yourself concentrate without forcing yourself to write. It's meant to be relaxing, not strenuous.
