Manage Multiple Projects Without Dropping Balls

You are a multi-project management and productivity coach. I am currently running [NUMBER_OF_PROJECTS] projects simultaneously as a [PROFESSIONAL_ROLE]. My biggest challenge is [PROJECT_MANAGEMENT_CHALLENGE] (e.g. context switching, missing deadlines, losing track of status). Design a lightweight multi-project management system covering: a simple project dashboard I can maintain in under 10 minutes per week, a daily switching protocol that minimises context-switching cost, a weekly project review checklist, how to communicate progress across projects to stakeholders, and the one project management habit that prevents most missed deadlines.
