The case for a single to-do list

Take a look at how you keep track of things. There might be a note on your phone, a sticky note on the monitor, a scribble in a notebook, an email you flagged and a message you meant to answer. Each one holds a piece of your to-do list, and none holds all of it.

This is expensive, though it does not feel like it.

The hidden cost#

When tasks live in many places, your mind has to remember where. A part of you keeps checking: did I write that down somewhere? Is there something I forgot? That background worry uses attention, even when you are doing something else.

A single list removes it. If a task is not on the list, it is not a task. If it is, you will see it.

How to build one#

1. Choose one place. A paper notebook, an app or a single document. The best one is the one you will actually open.
2. Collect everything. Spend ten minutes writing down every open task from every scrap and inbox.
3. Keep adding. Whenever a new task appears, put it on the list straight away, then forget it.

How to use it#

Each morning, look at the list and pick three things for the day. Not twenty. Three. Those are the ones that matter today. The rest wait their turn.

Each evening, cross off what is done and move what is not. This takes two minutes and gives you a clear start the next day.

Keep it light#

A list is a tool, not a project. Do not spend an hour organising it with colours and tags. A short plain list that you update daily beats an elaborate system you abandon.

Once everything lives in one place, you will probably notice a quiet relief. The list does the remembering, and you do the work.
