Stage 5: Daily Practice | Monthly Planner

A month is long enough to make real progress on something and short enough to course-correct when it's not working. Monthly planning gives you a structure for deciding what those somethings are, tracking the experiments you're running from Stage 4, and reflecting at the end of each month on what happened.

Use it at the start of every month. Spend 30 to 45 minutes filling it out. The best practices below will help you plan well, there's real research on why most people plan badly and what to do instead. The template section is the planner itself.

-HOW TO PLAN

Turns out that most people are not very good at monthly planning. Here's what the evidence says, and what to do instead.

We underestimate how long things take

Daniel Kahneman and Amos Tversky identified what they called the planning fallacy. People consistently underestimate the time, cost, and risk of future actions while overestimating the benefits. This isn't occasional optimism. It's a deep bias that persists even in people who know about it, Kahneman included, by his own admission.

Kahneman's later work with Dan Lovallo pointed to the fix: the outside view. Instead of imagining how your specific project will go this time (the inside view, which is where the bias lives), look at how similar projects have actually gone for you in the past. If your last three months each had a priority you didn't finish, the honest planning assumption is that next month carries the same risk, no matter how motivated you feel right now.

Simply ask yourself this: "How long did something like this actually take me last time?" And ask it before you commit to a timeframe, and use the answer, not your gut feeling in the moment. If you don't have a past data point, just build in more slack than feels natural.

The 3-priority rule

Edwin Locke and Gary Latham's goal-setting theory, built across decades of research and synthesised in their "American Psychologist", established that specific, challenging goals produce higher performance than vague ones like "do your best."

The idea that too many goals actively hurts you is a related but separate finding, closer to Robert Emmons's work on goal conflict and competition, which you've already met if you've worked through Focus Areas and Goals. Split attention across many priorities, and each one gets less of it, plus the priorities start fighting each other for your limited time and energy.

Three, as the exact number, is a practical convention, not a law of nature. It's the same logic behind the "OKR" habit of picking a small number of key results. But the underlying principle is real and well-supported: pick fewer things, and finish them.

So, pick 3 priorities per month, maximum. Not 3 categories with sub-goals hiding inside each. If you finish early, wonderful, add more then. Starting the month with 7 priorities means finishing it with 7 half-done things.

And yes, if you're ambitious, this is very hard. It feels like you're leaving things on the table, and you kind of are. But that's the point. The things on the table will still be there next month, and you'll get to them faster by not splitting your focus now.

Buffer time is not laziness

Leaving deliberate gaps in your month isn't slacking off, it's the only thing that makes the rest of the plan survive contact with reality.

First, the planning fallacy above cuts both ways. If you consistently underestimate how long things take, then a month scheduled at 100% capacity is a month that's already over budget before it starts. The buffer isn't optional generosity, it's the correction for a bias you now know you have.

Second, there's Sendhil Mullainathan and Eldar Shafir's research on scarcity, which you may recognise from the Resource Audit. They found that operating with no slack, whether in money, time, or attention, imposes what they call a bandwidth tax: it doesn't just limit your options, it measurably degrades the quality of your thinking and decisions. A month with zero unscheduled time isn't just fragile when the unexpected shows up (and it always does). It also makes you worse at everything else you're trying to do that month.

So a good monthly plan leaves real space unscheduled, roughly a week's worth out of four is a reasonable starting point, though there's no single magic figure here, adjust to what your month actually looks like. Some of that space absorbs surprises: the dentist appointment, the friend who needs help, the project that runs long. Some of it becomes the space where good ideas actually surface, because you're not grinding through a checklist.

If a fully open week makes you anxious, try scheduling your 3 priorities across 3 of the 4 weeks and leaving the 4th open to see what happens.

Connect monthly goals to your bigger direction

Kennon Sheldon's self-concordance research, which you met when you set your goals in Stage 4, found that goals connected to your own values and direction get more sustained effort and produce more satisfaction when achieved, while goals adopted from guilt or obligation drain you even when you hit them. So each monthly priority should trace back to something bigger: your focus areas, your vision, the goals you already set. If you can't explain why a priority matters to your broader direction, it probably doesn't belong on this month's list.

The second is about whether the goal actually gets done, once you've decided it's worth having. Peter Gollwitzer's research on implementation intentions, and the large meta-analysis he ran with Paschal Sheeran, found that specifying exactly when, where, and how you'll act on a goal produces a medium-to-large improvement in follow-through compared with simply intending to do it.

So the trick here is to choose priorities that are truly yours, then get specific about when and how you'll act on them. "Work on the business" is a wish. "Spend Tuesday and Thursday mornings on client outreach" is a plan.

The review is where the learning happens

Chris Argyris, the organisational theorist, introduced the idea of double-loop learning in a "Harvard Business Review" article. Single-loop learning asks: "Did I hit my goal?" Double-loop learning asks: "Was it the right goal? Are my assumptions still correct?" Most people only ever do the single-loop version, if they review at all!

At the end of each month, spend 20 to 30 minutes on the reflection prompts in this planner. They're built for double-loop thinking. They ask you to examine not just what happened, but whether your approach, your priorities, and your assumptions were actually right, including the possibility that you did everything correctly and it still wasn't the right thing to be doing.

Month overview

• Month:

• Theme or intention: One phrase that captures what this month is about for you

• How I want to feel:

Top 3 priorities this month

These should connect to your focus areas and goals from Stage 4. Three maximum. If you can't choose, ask which ones you'd regret not doing.

For each priority, ask why it matters, how long did something like this actually take you last time, and when and how you'll actually work on it.

Experiments running this month

From your Experiments section in Stage 4. What are you actively testing, and how will you know if it worked?

Habits to maintain or build

Keep this short. 3 to 5 habits maximum. More than that and you won't track any of them.
Note the exact habits, its frequency, and its anchor or triggers.

Commitments and deadlines

Things with hard dates. Things like appointments, deliverables, and events. Get them out of your head onto the planner.

My buffer this month

What am I deliberately leaving unscheduled? Roughly a week out of four is a reasonable start. Allow this week to absorb the unexpected and give yourself some thinking room.

What you're letting go of this month

Equally important as what you're adding. What are you deliberately not doing, not worrying about, or putting down for now?

AI companion (optional)

How to use: Run this after you've filled out the monthly planner. It works best when you paste in your actual answers rather than summarising them. The AI can spot overcommitment, vague goals, and blind spots you'll miss on your own.

Copy and paste the prompt below into Claude, ChatGPT, or any AI assistant alongside the current month, your 3 priorities, experiments you're running, what you're letting go of, and your buffer plan:

I want you to do three things:

(1) Check whether my priorities are specific enough to actually act on, or whether they're still vague wishes. Push me to make them concrete, including the when and how.

(2) Look for conflicts or overload. Am I trying to do too much given a realistic month, and does my reality check for each priority actually match the time I've allowed?

(3) Ask me one question I haven't asked myself about this month's plan.
