You should definitely pick up a copy of Wreck This Journal! Each page gives you instructions on how to destroy the book, and it's actually really cathartic and a lot of fun. The instructions range from cracking the spine to rubbing the book on a dirty car. It's a great creative project, especially for perfectionists. You really start to see the potential for beauty in destruction.
The instructions on one of the pages I did today was to write or draw with your left hand. So I did.
