Overview

This document consolidates all useful content from the .archives/ directory, spanning from August 2021 to January 2023. The content has been organized thematically and translated to English where necessary.

Workflow and Note-Taking Philosophy

Core Principles (2021-08-23)

1. Make notes easy and simple
2. Notes as a process of workflow, plus project management and GTD make Emacs the controller of work
3. Notes are merely part of the workflow, note networks are part of thinking, serving as a second brain

• Writing is thinking
• Tools help to do repetitive work
