Set Up Notion as a Personal Productivity OS

Act as a Notion workspace design specialist. I want to use Notion as my personal productivity operating system for my work as a [PROFESSIONAL_ROLE]. I want to manage [MANAGEMENT_AREAS] (e.g. tasks, projects, notes, goals, reference library). Design a complete Notion workspace structure covering: the top-level page hierarchy, the databases I need and their properties, how tasks, projects, and notes link together with relations, a daily dashboard view I can open every morning, and how to avoid over-engineering it so it remains usable after the first week.
