Only put tasks on the board that you’ve explicitly decided to do
Your Kanban board is not a wish list — only tasks you have consciously committed to belong in To Do.
Why it works
A Kanban board loses its function when the To Do column becomes an undifferentiated backlog of everything you might possibly do. A genuine To Do column contains only committed work — tasks you have decided are worth completing in the near term. This distinction mirrors the essentialism principle: having fewer items in the queue is a sign of better prioritization, not of having less work. A short, committed To Do column exerts appropriate urgency; an infinite backlog is just anxiety without direction.
How to do it
- Maintain a separate "Options" or "Backlog" area for tasks you haven’t yet committed to — keep it off the main board.
- Only move an item to To Do after consciously deciding it is worth doing in this planning period.
- Regularly prune the To Do column: if a task has been there for three weeks without moving to Doing, evaluate it honestly.
Evidence
The distinction between committed and uncommitted work is a foundational GTD principle (next-action vs. someday-maybe lists) and is consistent with goal-intention research: only committed goals receive implementation-intention-like follow-through. The Kanban version of this principle is practitioner design. (mechanistic)
Committed vs. uncommitted task management is a well-reasoned principle but not directly tested against undifferentiated backlog approaches in controlled settings.
Common mistake
Moving everything from a brain-dump brainstorm directly into the To Do column — which produces a Kanban board that looks productive but functions as an anxiety generator.

More practices for Personal Kanban, Made Practical
- Set up a simple To Do / Doing / Done board
Three columns and sticky notes (physical or digital) are all you need to make your work visible at a glance.
- Set and enforce a WIP (Work In Progress) limit
Limit yourself to two to three tasks in the Doing column at any time — never more, even when starting a new task feels easier than finishing an old one.
- Pull work rather than having it pushed to you
Choose your next task when you have capacity, rather than accepting whatever arrives first.
- Use the Done column to learn about your work patterns
Periodically examine completed cards for patterns in what gets done, what gets stuck, and how long things actually take.
- Watch for cards that stay in Doing without moving
A card that hasn’t moved in several days is a signal about a real obstacle — examine it rather than adding more work.
