In 20197ya I took a course called Building a Second Brain by Tiago Forte. Throughout the course I illustrated summaries of the main concepts which you can find below.
Much like it sounds, building a “second brain” is about creating a system – outside your physical skin-and-bone bodily boundaries – for storing, organising, and eventually transforming information.
This idea is not especially new; commonplace books for storing personal knowledge have been around for centuries. Although digital mediums have made it easier and faster to capture, browse, search, and retrieve the information in these systems.
