And how do you manage it?

I bought today a blank notebook and wrote some concepts on random pages (the gratitude page, few pages about my city, idiot collection, page of hopes, page of fears, bad news page, some places for drawing, mood word page, dream journal, things that saved my life, good people list). I noticed I made more negative/cynical pages, but might be not a bad thing, since I may need to get it out of my system.

I also have place for the "project" of hopping on random tram and going to the final stop and writing about it. And page for nail polish swatches, just cause....

Ever tried such thing? A journal you carry around and do random stuff with it? What things you done?
