I bought the 'wreck this journal' showed it a friend and she's going to get one for herself and each of her daughters. What it isn't, is a model for an art journal e.g. day pages, representation of an event, scrapbook etc. For me this is more about breaking the normal rules of what you do with a book, see pages on 'flickr'for examples/ pictures of what other people have done with their journals. You can also go on the authors website to see ideas/ examples. Each page has an instruction on a way to alter/wreck a page/ the cover/ binding, for example doodle on the cover, tear a page out, put it into the pocket of your clothes and put it in the washing machine, when you've done that stick it back in the book. It reminded me of an art installation I went to see some years ago of some flowers in a case that were left in a window for weeks. The artist actually wanted to see the process of decay and how that would look. The flowers were dried up and crumbling when I saw them, but had their own kind of beauty.
If you are a bit of a perfectionist and are scared of the blank page or don't like to break the rules this should free you up a bit. The book isn't that expensive so it's kinda liberating to take it in the shower with you and see how it looks when you're done. I'm taking pictures of the process and will put it on my facebook page when I'm done. It's a fun exercise in loosening up and I would recomend it on that basis.
It's also interesting to note which instructions you are resistant to, I'm really struggling with the idea of tying a string round it and taking it for a walk - not least because the neighbors will think I'm mad LOL. And I really don't want to give a page to a friend to wreck it. Tells you a lot about yourself and what you are prepared to let go of and what you are not. It may also unblock you creativitly speaking - that's what I'm hoping for.
