How to Use the Someday/Maybe List for Better Productivity

Most productivity advice lives in a binary world: either you act on something or you delete it. Commit or cut. Do or die.

But anyone who has ever scrapped a project idea only to spend the next three months quietly mourning it knows that "delete everything uncertain" is terrible advice for creative, idea-heavy people.

The someday/maybe list — a concept popularized by David Allen in Getting Things Done — offers a third path. It's not a commitment. It's not a trash can. It's a designated holding space for possibilities that aren't right now but might be exactly right later. Used well, it dramatically reduces decision fatigue while keeping your creative energy intact.

This guide breaks down exactly how to use it, how to keep it from becoming a graveyard of forgotten ideas, and why it works especially well for overthinkers.

Why "Act or Delete" Fails Idea-Heavy People

The classic productivity model assumes that everything in your system should either have a next action or be thrown away. Clean inboxes, zero-based task lists, ruthless prioritization.

For a certain kind of person — project managers executing well-defined work, say — this is fine. But for writers, entrepreneurs, designers, researchers, and anyone whose job involves generating and evaluating possibilities, the act-or-delete model creates a specific kind of harm:

It forces premature decisions on ideas that aren't ready to be decided.

When you're staring at "learn Portuguese" or "start a podcast about urban foraging" or "explore a pivot into consulting," you don't always know yet whether these are good ideas or not. They need time to breathe. They need you to encounter a few more data points, finish a current project, or simply sleep on it for a month.

Forcing an immediate yes or no on every idea doesn't make you more productive. It makes you anxious and indecisive, or it makes you artificially committed to things you haven't properly evaluated.

The someday/maybe list solves this by giving uncertain ideas a legitimate home — one that is outside your active task system, so they don't create noise, but inside your trusted system, so they don't get lost.

What the Someday/Maybe List Actually Is

At its core, the someday/maybe list is a single, dedicated collection point for any project, goal, or idea that:

You're genuinely interested in but not ready to act on
Has unclear timing ("when I have more bandwidth," "when I finish the current project")
Needs more information before you can commit
Is speculative, exploratory, or aspirational

It is not a dumping ground for things you'll never do. That distinction matters. If you already know you'll never learn to play the cello, don't put it on the someday/maybe list — delete it. The list works because it contains items you have real, honest interest in, not items you're keeping out of guilt or fear of missing out.

The list can include things like:

Side projects and business ideas
Books you want to write or read
Skills you want to develop
Travel you want to do
Collaborations you want to explore
Systems you want to build once you have the capacity

How to Build Your Someday/Maybe List Without It Becoming a Black Hole

1. Create a Clear, Dedicated Space for It

The someday/maybe list needs to live somewhere specific — not mixed into your active task list, not buried in a notes app you never open, and not floating around in a dozen different places.

Whether you use a physical notebook, a task manager, or a notes app is less important than consistency. The rule is: one place, always the same place. When an idea qualifies for someday/maybe, it goes there and only there.

Keeping it separate from your active work is non-negotiable. The whole point is to remove these items from the cognitive foreground so they stop generating low-level anxiety while remaining accessible when the time is right.

2. Lower the Bar for Capture, Raise It for Action

One of the most counterintuitive rules of the someday/maybe list productivity approach is that you should be generous when adding items and strict when promoting them.

Capturing an idea costs almost nothing. If something crosses your mind with even a flicker of genuine interest, add it. The list is cheap real estate. You're not committing to anything by writing it down — you're just ensuring the idea doesn't get lost in the noise.

What you protect carefully is promotion: moving an item from someday/maybe to an active project with next actions. That step requires deliberate evaluation, not impulse.

3. Review It on a Regular Cadence — But Not Too Often

The someday/maybe list only works if you actually revisit it. Without regular review, it becomes exactly what you feared: a digital landfill where ideas go to die quietly.

David Allen recommends reviewing it during your weekly review — a dedicated time each week to process your system, close loops, and plan ahead. During this review, you ask:

Has anything on this list become timely or relevant?
Do I have capacity to activate any of these?
Is there anything I can now honestly say I'll never do?

You're not trying to act on everything. You're just making sure the list stays alive, current, and honest. Items get promoted, deleted, or left alone — all valid outcomes.

If weekly feels too frequent and you find yourself breezing through without making changes, monthly is fine. What matters is that the review happens consistently.

4. Give Each Item Enough Context to Be Useful Later

A bare-bones entry like "podcast" or "Spain" or "consulting" will be nearly meaningless in three months. When you add something to the someday/maybe list, spend thirty seconds adding context:

Why does this interest you?
What would need to be true for you to act on it?
What's the simplest next step if you ever do decide to move forward?

This small investment pays enormous dividends during review. Instead of staring at a cryptic note and spending five minutes trying to reconstruct your original thinking, you have just enough information to make a quick, informed decision.

5. Keep Sub-Lists When the Main List Gets Unwieldy

If you're a prolific idea generator, your someday/maybe list can grow large quickly. Once it hits forty or fifty items, the sheer volume starts to work against you — reviewing it begins to feel like a chore rather than a creative check-in.

One practical solution is organizing by category or context:

Someday/Maybe: Creative Projects
Someday/Maybe: Professional Development
Someday/Maybe: Travel
Someday/Maybe: Home/Personal

This way, during a work-focused review, you can quickly scan the professional categories without wading through your entire bucket list. The structure reduces friction without limiting what you capture.

The Psychological Reason This Works for Overthinkers

Overthinkers don't struggle with having ideas. They struggle with what to do with them.

Every unresolved idea sitting in the back of your mind creates what psychologists call an "open loop" — your brain keeps returning to it, trying to resolve it, even when you're trying to focus on something else. This is the Zeigarnik effect in action: unfinished tasks demand more mental bandwidth than completed ones.

The someday/maybe list closes the loop without forcing a decision. When you capture an idea there, your brain registers it as handled — filed, not forgotten. The low-level cognitive hum quiets down. You're no longer losing processing power to an unresolved possibility.

This is why the someday/maybe list productivity system is particularly valuable for people who identify as overthinkers or who work in highly generative roles. It gives their brains permission to let go, knowing the idea is safe.

Common Mistakes That Kill the System

Using it as an avoidance mechanism. If you're adding things to someday/maybe specifically to avoid making hard decisions about them, the list becomes procrastination in disguise. Be honest with yourself: is this genuinely uncertain, or are you avoiding a clear "no"?

Never reviewing it. A someday/maybe list you never revisit is just a longer to-do list you feel guilty about. Build the review into your weekly or monthly rhythm and treat it as non-negotiable.

Mixing it with your active projects. The moment someday/maybe items share space with your current tasks, you've collapsed the boundary that makes the system work. They will start generating anxiety again immediately.

Adding things you don't actually care about. If you feel obligated to be interested in something rather than genuinely curious, skip it. Guilt-driven additions pollute the list and make it harder to trust.

Promoting an Item: When Someday Becomes Now

The graduation ceremony for a someday/maybe item is simple but important. When you decide to move something to active status during a review, it needs three things:

1. A clear project definition — what does done look like?

2. A next physical action — what is the very first concrete step?

3. A place in your active system — it gets added to your project list and scheduled or queued appropriately.

Without all three, you're just moving an idea from one holding area to another. The next action is particularly critical — it's what transforms a vague aspiration into something your future self can actually execute.

Making Peace With Uncertainty

There's something quietly radical about the someday/maybe list that goes beyond productivity mechanics. It acknowledges something true about how humans think and grow: not every good idea is a good idea right now, and not every uncertain thing deserves an immediate verdict.

Using the someday maybe list as a productivity tool isn't about avoiding commitment. It's about making the right commitments at the right time, with enough information and capacity to follow through. Everything else gets held respectfully, reviewed periodically, and acted on when the conditions align.

For anyone who has ever felt crushed by the pressure to either act on every idea or abandon it forever, that's not a small thing. It's a different relationship with possibility itself — one that's more honest, more sustainable, and ultimately more productive than forced decisiveness ever could be.
