This document introduces the concept of personal kanban, a lean principle for visualizing and limiting work-in-progress to simplify one's workload. It discusses how the presenter used a kanban board to map out tasks from to-do lists and emails into different categories, priorities, and stages to gain control over their work. Applying concepts like recurring tasks, a value stream, and regular cleaning helped establish a sustainable personal workflow. The document encourages readers to try these lean techniques to better execute on what matters and say no to unnecessary work.
