A most deathly serious question for all writers out there.

I refer of course, to our notebooks. For example, my current notebook is a small 100 page spiral bound affair, currently half full with the demented scribblings that not even the most dedicated pharmacist can decipher. I can however, and what I see often makes me ask myself "WTF
was I thinking?!?"

Even worse are the sketches of characters and places from my books. (my drawing is a skill I haven't taken seriously in years.) This current abomination is used by me to keep characters and brainstorming seperate and fresh in my memory; each story has a page or two.

In college my notebook was a leather bound book with heavy gauge paper stock in which I'd painstakingly write poems with honest to the gods calligraphy. I have owned a few of varying types since.

So, show of hands, or maybe even pictures, which writers here have notebooks?

As a side note, which writers here have posted a story, went home, and immediately written 1k words or more on a brand new story... knowing all the while what a bad idea that was?

Yeah, guilty.
