Elimination Planning: A Different Way to Prioritise Your Day

Most to-do lists grow. You add the new task, the follow-up, the thing your manager mentioned in passing, and by Wednesday the list is longer than when the week started. Elimination planning works the opposite way: instead of asking what to add, you start each planning session by deciding what to remove, and only then look at what's left.

The common advice — prioritise by urgency, or rank everything 1 to 10 — assumes every item on the list deserves to be there. It doesn't ask the harder question: which of these tasks would cost you nothing if you simply stopped doing them?

Elimination planning works because removing a task is a one-time decision that pays off every day afterwards, while prioritising a growing list is a decision you have to remake constantly. Think of it like a wardrobe you can barely shut. You can wrestle the door every morning trying to squeeze in today's outfit, or you can spend one Saturday afternoon clearing out what you no longer wear. The clear-out costs you an hour once; the daily wrestle costs you a few minutes forever, and those minutes add up. This article covers the mechanism behind why subtraction beats addition, and a practical protocol for running it weekly.

What elimination planning actually is, mechanically

Elimination planning means actively identifying tasks, meetings, and commitments to stop doing entirely, rather than only ranking what remains. It draws on the Pareto principle — the observation, first made by economist Vilfredo Pareto and later generalised across many fields, that roughly 80% of outcomes tend to come from around 20% of inputs. Applied to a task list, this means a large share of your effort each week is likely going toward the low-impact 80%, and no amount of clever prioritisation fixes that; only removal does.

The mechanism is opportunity cost, made visible. Every task you keep is a task you're implicitly choosing over something else, including rest. Author Greg McKeown, in his work on essentialism — the idea of doing less, but doing it more deliberately — frames this as: if something isn't a clear yes, it should be treated as a clear no. Ranking a list keeps everything technically alive. Elimination forces the actual decision.

Why ranking everything doesn't work

Standard prioritisation — numbering tasks by urgency or importance — assumes the problem is sequencing. It isn't. The problem is usually volume: too many legitimate-looking tasks competing for finite hours. Sorting a 40-item list into order doesn't make it a 15-item list. It just tells you which order to fail to finish it in. It's a bit like rearranging fifty open tabs on your phone into a tidier order — it might look calmer, but your battery drains at the same rate, because you haven't actually closed any of them.

There's also a cost to the ranking itself. Research on decision fatigue, including early work by psychologist Roy Baumeister on self-control depletion, suggested that each decision draws on a limited resource that depletes across the day — though later replications have questioned how large this effect really is. What's less contested is the practical experience: deciding what order to do fifteen things in, every single day, is itself a task, and a tiring one. Deciding to remove five of them once removes that daily cost for good.

The layer most productivity advice misses

Most planning advice treats every task as equally real once it's written down. It isn't. Some tasks exist because they were once useful and nobody revisited them. Some exist because saying no felt awkward in the moment. Some exist because they look productive without being productive — the meeting that generates no decisions, the report nobody reads twice.

The investor Warren Buffett's well-known "two-list" approach to priorities — write 25 goals, circle the top 5, and actively avoid the other 20 rather than working on them opportunistically — illustrates the same principle: a list of good options is not the same as a list of the right options, and the ones you deliberately avoid matter as much as the ones you choose.

What actually works: the elimination protocol

This isn't about doing less for its own sake. It's about spending your actual hours on the fraction of tasks that carry most of the value.

Run a weekly elimination pass before you plan the week

Before adding anything new, list everything currently on your plate and ask one question per item: what happens if this simply doesn't get done? If the honest answer is "nothing meaningful," cut it. Do this before, not after, ranking what's left — elimination first, sequencing second.

Separate "someone should do this" from "I should do this"

Many tasks survive because they're vaguely useful to someone, not specifically necessary for you. If a task exists mainly to be seen doing it, question it directly. A structured system such as the Priority Pad forces this distinction by giving you a fixed, limited number of daily slots — which makes the cost of keeping a low-value task visible rather than hidden in an endless list.

Apply a one-in-one-out rule to recurring commitments

Before saying yes to a new standing meeting or recurring task, name what you'll remove to make room for it. This stops the list from silently regrowing the moment the elimination pass is over.

Review what you eliminated after two weeks

Check whether anything you cut actually caused a problem. In most cases, nothing happens — which is the evidence that it wasn't essential. This step matters because it builds the confidence to cut more decisively next time.

What to stop doing

Stop ranking before you cut. Sequencing a bloated list wastes effort that should go into shrinking it first.

Stop keeping tasks out of guilt. A task kept because removing it feels uncomfortable is still costing you the same hours it always did.

Stop treating busyness as evidence of value. A full list looks productive and often isn't — volume and impact are not the same thing.

Stop adding without subtracting. Every new commitment should force an honest look at what it's displacing.

When to Take It More Seriously

If your task list feels unmanageable no matter how much you cut, or if you find you can't say no to anything without significant anxiety, that's worth examining beyond a planning technique. Chronic overload that doesn't respond to structural changes can be a sign of burnout or an underlying anxiety pattern rather than a scheduling problem. If this is affecting your work, relationships, or daily functioning, speak to your GP. They can refer you for assessment or, where appropriate, a course of evidence-based therapy.

In the UK, you can self-refer for CBT (cognitive behavioural therapy, a structured, practical talking therapy) and other evidence-based therapies via your local NHS Talking Therapies service at nhs.uk. For ADHD-specific concerns, you can pursue a private diagnosis via the Right to Choose pathway — ask your GP for a referral to a specialist such as Psychiatry UK or ADHD 360.

Frequently Asked Questions

What is elimination planning?

Elimination planning is a prioritisation method where you actively decide what to stop doing before ranking what remains, rather than only sorting an existing list by urgency or importance. It's based on the idea that a large share of typical daily tasks contribute little value, and removing them has a bigger effect than reordering them.

How is elimination planning different from a normal to-do list?

A normal to-do list assumes every item deserves a place and just needs sequencing. Elimination planning starts by questioning whether an item deserves to be there at all. The practical difference is a weekly elimination pass done before planning the week, rather than only ranking tasks each morning.

Won't I miss something important if I eliminate tasks?

In practice, most eliminated tasks turn out not to have been essential — checking back after a couple of weeks usually shows nothing went wrong. Elimination planning isn't about cutting blindly; it asks a specific question per task (what happens if this doesn't get done?) rather than removing items at random.

Is elimination planning suitable for people with ADHD?

Many people with ADHD find elimination planning particularly useful, because a long undifferentiated task list increases decision fatigue and task-switching cost, both of which are harder to manage with executive function differences. Reducing the list to fewer, clearer commitments can lower the cognitive load of simply deciding what to do next.
