Closed Lists
A constraint-based task management approach that limits an active to-do list to a fixed set of tasks, allowing no new additions until current items are completed. This technique prevents the perpetual growth that makes traditional to-do lists feel unmanageable.

Overview
Closed Lists are a task management approach where you maintain a fixed, bounded set of tasks and refuse to add new items until at least one existing task is completed. This creates a 'one out, one in' discipline that prevents the common problem of ever-expanding to-do lists.
How It Works
- Write down a fixed number of tasks you will commit to finishing (e.g., 5-10)
- Do not add any new tasks to the list until one of the current tasks is completed
- When a task is finished, remove it and only then may you add a new task
- This creates a constrained, manageable workload
Benefits
- Prevents to-do list bloat and the overwhelm that accompanies it
- Forces prioritization: new tasks must be actively compared against existing commitments
- Creates a psychological sense of closure and progress
- Encourages completion rather than endless accumulation
Origin
The concept is prominently advocated by writer Oliver Burkeman in his book 'Four Thousand Weeks: Time Management for Mortals,' where he argues that constraints are essential to realistic and humane productivity practices.
