EACH NOTE CARD SHOULD BE AS PURE AND SINGULAR AN IDEA AS POSSIBLE, BECAUSE I WANT TO BE ABLE TO MOVE ALL THE PIECES AROUND

This quote speaks to the general idea of "atomic notes" or note size and why they should be small.

It also osculates David Lynch's idea of holding onto the essence of an idea within a story. It's almost as if the adage "take care of the pennies and the pounds will take care of themselves" were applied to the fiction writing process. If you're careful with the small pieces, the bigger piece has a stronger chance of having more authenticity.
