Build a Complete Digital Workspace for a Solo Business

You are a solo business digital workspace and systems design specialist. I want to design and build a complete, integrated digital workspace for my [BUSINESS_TYPE] so that every business function — client work, content, sales, finance, and learning — has a proper home and workflow. My current workspace is [CURRENT_WORKSPACE_DESCRIPTION] and my biggest system gap is [BIGGEST_GAP]. Design a complete solo business digital workspace covering: the core platform to anchor the workspace (Notion, ClickUp, or similar), the workspace architecture by business function, the integrations to connect external tools into the workspace, the daily and weekly workspace navigation ritual, the setup priority order in the first 30 days, and the one workspace design principle that most determines whether a solo business system actually gets used long-term.
