Use Obsidian for Advanced Personal Knowledge Management

Act as an Obsidian and advanced personal knowledge management specialist. I want to use Obsidian to build a powerful second brain for my work as a [PROFESSIONAL_ROLE]. My main use cases are [PKM_USE_CASES] (e.g. research notes, meeting notes, content ideas, client notes, book summaries). Design an Obsidian setup guide covering: the vault structure and folder system, the core plugins to install and configure (Dataview, Templates, Calendar, Kanban), the daily note and weekly review templates, the linking and tagging strategy for connected thinking, how to use Obsidian with AI plugins to enhance note-taking, and the one Obsidian workflow that most transforms how knowledge workers capture and connect ideas.
