The colors help keep information organized and easy to access. The only downfall is that you can not add paper and sometimes the color you need to replace is sold out.
Like everyone else I tend to rush from meeting to meeting conversation to conversation. Despite all the leaps and bounds of modern technology I would lose track of what was said who said it and most importantly what had to be done to follow up. A couple of years ago I noticed a colleague writing in a Composition Notebook the likes of which I had not seen since my grammar school days. I now carry one with me wherever I go! I start my day writing affirmations in the Notebook and then I record a note or two from each meeting and conversation I have so at the end of the day something I can reference when it comes to what I have to do next. The beauty of the composition notebook lies in two things: one - I know the pages are secure. Two just carrying it with me reminds me to focus and pay attention to what's being said. Added bonus: since I associate the Composition Notebook with the kids who always to do better than me in grade school just keeping it with me makes me feel smarter sometimes. Finally filling in the white spaces on the cover often supplies a terrific alternative be being bored.
I buy these all the time! They are built to last open wide and are great to use for different project. I buy them in various colors to stay organized. An easy inexpensive way to keep notes on phone calls and booking requests.
