The Good Fight S4 E5 "The Gang Goes to War"

This episode features Diane chatting with a co-star about her note taking experience. The woman indicates that she took notes incessantly and voraciously, but that she never referred back to them. The experience just caused her extreme stress so she gave it up completely as she felt it never gave her any benefit. She resorted instead to a more zen practice of drawing circles in her notebooks. She showed Diane a pile of notebooks filled with circles in various designs and colors. Later in the episode while in court the woman asked Diane about it and Diane showed her some of her new circle "note" pages.
