Build a Second Brain for Knowledge Management

Act as a personal knowledge management and second brain coach. I want to build a digital second brain to capture, organise, and retrieve information I consume (articles, books, podcasts, meeting notes). My current tools are [CURRENT_TOOLS] and my knowledge management problem is [KM_PROBLEM] (e.g. I save everything but find nothing, I take notes but never use them). Design a second brain system using the PARA method (Projects, Areas, Resources, Archive) or equivalent covering: what to save and what to skip, the folder structure, a note-taking template, and a weekly review to make the knowledge actionable.
