Sometimes, you just need to let go of everything nice and beautiful and create a mess before you are able to create at all!
That was my idea when I lost my mojo and was unable to express any creativity. I came across the book "Mess" by Keri Smith and ordered it from the Bookdepository.
The idea behind the book is that you are not only allowed, but encourage d to make a mess of the book itself.
That was an easy one! I just had taken out a tin with loads of pencils and started doodling in colour! The workspace became a beautiful mess as well. :-)
