How I invented a daily planner

The author shares their experience with the Zettelkasten method and the popular tool Obsidian. Despite the appeal of the 'second brain' concept, the author concluded that a complex network of linked notes is not always effective for daily tasks. While the method proved useful for structured educational courses, it failed to improve long-term retention or deep understanding of topics. After years of experimentation, the author simplified their workflow to a 'one day, one note' format. This experience highlights that complex knowledge management systems can be redundant, and sometimes a simple chronological log is more productive than attempting to build a knowledge graph. The article encourages readers to critically evaluate productivity tools and adapt them to their actual needs rather than blindly following trendy methodologies.
