1. It is easy to find - especially if you buy one with a bright cover. Ever lost a note? - it's harder to loose a whole notebook
   
2. You can't accidentally throw it away. (Okay maybe you could, but then your life is probably going crazy if you throw away a notebook) Sticky notes are by nature sticky - meaning they can stick to things and end up in the trash
   
3. It is easy to refer back to - make notes when you are on the phone, or remember something important. It is a bit of your brain on paper. Amazingly I sometimes can't remember exactly what was said but I remember where I wrote it
   
4. It looks a lot neater than a bunch of pieces of paper on your desk

How do you use a spiral notebook? While I'm sure you will find your own style, this is what I do:

1. Use one side for a continual "to-do" list. This comes in handy especially when you are involved in a Real Estate transactions. Add and cross items off until the page is unrecognizable, then flip to the next clean page and rewrite those items not done.
   
2. Start at the other end and write notes on the back of the pages. This can be ideas you thought of; conversations with contractors, vendors etc. Make sure to date each item to help you decipher it in the future. This also helps when you have to make another call and say on "this date you said" - that helps things spring into action.

And yes, I know Outlook and other programs have "to do" lists, and I can keep notes there (and I do), but there is something satisfying about scratching an item off a list AND you can't doodle in note taking programs....and that's half the fun!
