Hi, this may sound like a stupid question but it's for fun :P?

I received two notebooks for Christmas but they look really nice and I don't want to let them go to waste, they don't have dates or anything on the paper, it is just printed paper (e.g the Hello Kitty one has Hello Kitty on it, ditto with the Mickey Mouse one!) What kind of things do you write in these sorts of notebooks as I don't want to keep a diary and as I said I don't want it messy so would rather not write things then rip the paper out. Btw I'm a teenage girl :P!
