Zettel

A Zettel is a note or piece of information you write down to organize your thoughts, ideas, or knowledge. Originating from the German word for "slip" or "note," it serves as a building block for a personal knowledge management system. Each Zettel is typically concise, focused on a single idea, and can be linked or linked to other Zettel, creating a web of interconnected notes. This approach helps enhance understanding, facilitate creative thinking, and make retrieval of information more efficient, especially when managing complex or large amounts of knowledge.
