#🧠knowledge >Your mind is for having ideas, not holding them. *-David Allen* --- In the realm of productivity and [[knowledge work]], the term "second brain" is often attributed to [Tiago Forte](https://www.buildingasecondbrain.com/), who popularized the idea through his book and courses. The core idea is to use modern technology to expand our ability to store and process information: - **store** knowledge and ideas outside your head, ensuring the information is not forgotten, whiles little energy is required to remember it. - effectively **navigate and process** the various ideas, inspirations, and insights across your knowledge domain and the connections between them. The concept is built upon earlier ideas, such as David Allen's Getting Things Done (GTD) methodology, which emphasizes the importance of moving tasks and information out of the mind and into a trusted system. The second brain concept extends beyond task management to encompass the broader management of knowledge, ideas, and information. [[Zettelkasten]] method aligns closely with the second brain concept, particularly in its aim to externalize memory and thought processes into a structured, retrievable system. The concept of second brain is also related to the ideas behind [[tools for thought]] - an endeavour to harness technology for more effective knowledge management and cognitive augmentation. Indeed, "second brain system" may serve as an augmentation of one's cognitive processes, increasing the biological brain's capacity for imagination, creativity, and mere presence. --- ## References - [Building a Second Brain: The Definitive Introductory Guide](https://fortelabs.com/blog/basboverview/) --- <font style="color: #F86759">Contributors:</font> *[[Jaros]]* <font style="color: #F86759">Last edited:</font> *2024-03-03*
