Pile of Index Cards

From a curiosity, I wonder how many cards I wrote this year. Here I use indexcards in the “life” dock as a sample for simplicity. The card system for “work” is extended PoI and more complicated than “life”.

Since it takes some time to count them one by one, I used trick to count easily.

1. Measure a weight of the cards of each month, by using a scale.
2. Divide the weight by 1.5, that is a weight of single card in gram (150g for 100 papers).

That’s all. This is another advantage of using indexcard :)

I measured a weight of cards of each month. The figure above is a number of card per month, since February 2006. It was when I start using 5×3 quadrille card. Total and mean are summarized in a table below.
