Staples Columnar Book helps me to see the big picture. I have been using it to compile data for as long as I can remember. It certainly saved my data when my computer crashed. I wouldn't be efficient without it.
I'm using this to organize my brain as well as my household finance. I can't store numbers in my head anymore although I can still solve quadratic equations thanks to a great math at my high school. Too many head injuries I guess. I will be able to enter relevant figures into excel later for analysis --DC 73
I have been using the 13 column book for years... I do like that better than the 12... the 13 allows me a space for the TOTAL of the 12 months I record.
