Since starting using a Zettlekasten while reading books, I decided that (really good) old books deserve to be read again as their knowledge will not be lost. By leveraging the Zettlekasten I hope to connect new and old ideas and extract new wisdom.
The first book I re-read is 7 habits for highly effective people of Stephen R. Covey (the R is important)
My current setup for the Zettlekasten is based on
- 5x3" Record Cards
- [a card box ](Q Connect Card Index Box, 5 x 3 Inches - Black)
And a card look like this
With the top left number being the index of the card (I use sequential numbers), the ref 82 means that the initial idea came from the book described in the card 82 (The Trusted Advisor) and the trust equation is documented in card 60.
Two books got me to 150 cards more or less.
