I like your idea of reserving the bottom part of the page.
Right now I review only when I'm off, when something feels wrong. But that's part and parcel to how I've approached doing the journal anyway, which is sort of grudgingly and unwillingly and, if something goes wrong, looking back in irritation and judgment (though usually when I see the reason I am relieved and pleased.)
At any rate, I want to be more proactive in how I review. I like your idea of a daily review. I was just wondering if there were mechanical things other people did - I went back and re-read my old SARP book on journaling and there were individuals who talked about sparkly crayons and stickers and highlighting. I like the idea of a visual thing where I could see in non-verbal form when I open up a page what exactly happened that day.
But for now I think I'm going to do the bottom part of the page thing. I will need a bigger journal, though, since mine's small so it fits in my purse and I usually use it all up by the end of the day.
Thanks for sharing what you do, mosaic!
