Think beyond one “second brain” – consider building many. With AI tools like NotebookLM, you can capture knowledge fields and create entire libraries of minds and themes to tap into whenever needed.
The idea of a single “second brain” has inspired millions to organize their notes, bookmarks, and half-finished ideas in apps like Notion or Obsidian. However, when juggling multiple projects and sources of inspiration, one brain can quickly become overwhelming. That’s why it’s time to think bigger – building many brains that cater to your interests and needs.
To start, choose someone you admire and collect their work. Whether it’s a podcast transcript, PDF book, or blog post, upload everything into NotebookLM. The platform organizes these documents into an interactive, conversational space where you can engage with the content.
Next, treat this new brain like a personal coach – ask questions, run ideas by it, and get responses that feel like direct advice from your idol. You can also expand this approach to themes, creating notebooks for topics like leadership or creativity.
By adopting these strategies and using AI tools like NotebookLM, you’ll unlock the power of multiple brains. Remember to uphold integrity when working with artificial intelligence, respecting intellectual property and perspectives.
The future of knowledge is interactive – don’t settle for a single second brain. Build many, capture the minds that matter, and let AI tools like NotebookLM help you activate your knowledge into something useful.
