The speaker's process of collecting notes has changed since taking the note-making mastery class. They have been a voracious reader for many years and used to struggle with remembering the value of books they read in the past. However, after the class, they started tagging their books and carrying a pocket-sized notepad to write down their thoughts while walking. They have also adopted the notion app to organize their notes in multiple places and easily access them through simple searches. This new approach has helped the speaker categorize their notes and have them readily accessible in one place.
