Your schedule tells you where the day went. It does not answer why you are empty in the evening even when nothing big happened — or why after a packed day you sometimes arrive home recharged. The difference is not explained by time but by energy, and that can be measured in a week.

Why a schedule is not enough

Time is a comfortable measure because everyone has the same amount of it and it is easy to add up. But two hours of equal length do completely different things to you: after a good conversation you can be fresher than before, and after twenty minutes of admin emptier than after two hours of work.

If you only look at time, none of this shows. What shows is that your day was full — and the conclusion is to take on less. Very often, though, the problem is not the quantity but the composition: a few specific items take a disproportionate share, and those can be swapped or moved, whereas your whole day cannot.

So an energy map is not a calendar. It is not interested in how long something took, but in what state it left you in.

The measurement: seven days, three entries a day

The most common mistake is measuring too often. You will quit hourly notes on the second day, and the data will be skewed anyway, because measuring itself takes energy. Three a day is enough, and each takes half a minute.

1. Late morning, once. When the first big block ends — the meeting, the school run, the first two hours of work.
2. Afternoon, once. Typically around the low point of the day, when you would reach for coffee anyway.
3. Evening, once. Not at bedtime but when the “obligatory” part of the day has closed.

Every entry consists of two things. A number from minus three to plus three — it does not measure whether it was good, but whether you have more or less energy than before. And half a sentence about what happened in between. That is all.

Four kinds of drain — and the one we never notice

By the end of the week the entries will fall into four groups. The first three are familiar; the fourth is a blind spot for most people.

1. Task. The activity itself drains: the admin, the forced decisions, long concentration. This is the easiest to see, and that is why we blame it.
2. People. Not people in general but specific people — or specific situations with specific people. This is the most uncomfortable category, and typically the most accurate.
3. Environment. Noise, light, temperature, where you sit. Undervalued, because it does not feel personal — yet it acts on you for hours a day.
4. Transition. Not the task but the switch between tasks. This is the invisible fourth: it is not in the calendar, it has no name, and it cannot be remembered. It still takes the most from many people.

The transition does not show because it has no start and no end. If you switch between radically different kinds of task seven times in a day, you are rightly exhausted in the evening — while “nothing big happened”, and your calendar shows only seven ordinary entries.

What drains is not what is hard

This is the most surprising result of the measurement, and it comes up for almost everyone. Hard, concentration-demanding work often closes with a plus, while something short and seemingly trivial closes with a minus.

The difference typically turns on three things. Whether you had control over the situation or only endured it. Whether it had a close, or stayed open. And whether you had to play a role that is not you.

That is why “reduce your load” does not work on its own. If you take away the hard work while leaving the seven unfinished small things, you will work less and arrive home just as empty.

What you will see at the end of the week

On Sunday sit down for ten minutes with the twenty-one entries. You do not have to analyse, only find three things in them.

• The two biggest minuses. Not the most frequent but the biggest. Start with these, because moving one big item is worth more than five small optimisations.
• What was a plus and surprised you. This is the most valuable line of the week. There is typically at least one — and typically something you had not thought important.
• The time of day. Check whether the minuses cluster in time. If they do, your business is not with the activities but with your daily rhythm.

After one week do not try to rebuild everything. One change is enough — and the good change always starts with the biggest minus, not the easiest one.

Three interventions that actually work

Once you have the two biggest drains, there are three things you can do with them. It is worth trying them in order, because we tend to skip the first.

1. Deletion. The most frequently skipped option. Not every drain is necessary — plenty of things are in your day because they got in there once. Before optimising, ask what would happen if it simply were not there.
2. Grouping. If it cannot be deleted, put it in one place with the others like it. This lowers the transition cost, which — as above — is the invisible item. Four small administrative things in one block cost considerably less than four separate occasions.
3. Pairing. What can be neither deleted nor grouped, put next to something that fills you. Not as a reward — but so the minus does not land on an already exhausted state.

The plus column nobody uses

After the measurement almost everyone does the same thing: they go for the minuses. That is understandable but one-sided — the plus column holds much rarer information, and much cheaper to use.

Removing drains is typically expensive: you have to give something up, talk to someone, reorganise a day. Multiplying what fills you is almost free — there you already know it works, it has just happened at random so far.

So at the end of the week go through the plus lines separately and ask one question: “what made this good, and what part of it is repeatable?” Typically it is not the whole situation that repeats but one element of it — that you were alone, that it had an end, that somebody thanked you, that you were outdoors. Building one element into the rest of the week changes more than removing one drain.

And a warning: a good share of the plus lines do not come from work. That is sometimes an uncomfortable realisation, because it suggests most of your week does not fill you. But that is not a ruined life — it only means the filling elements have to be scheduled deliberately, not left as a residue.

When everything drains

There is one result worth naming separately: if by the end of the week nearly every entry is a minus and the plus column is empty, then the map is not about your energy budget.

Then the question is not what to regroup. General joylessness, continuous exhaustion and nothing filling you — together these are signs that are not to be solved by organisation. Our article on the signs of burnout covers this in detail, including when it is worth seeing a professional.

The energy map is not useless then either — its role is just different. It becomes not a planning tool but evidence: something you can show, and with which you do not have to argue from memory that you really are not well.

How to do it in Mirrify

Mirrify has a separate energy page where the measurement is not a separate chore: it is recorded alongside the daily entry, so you do not have to check in somewhere else. At the end of the week you do not turn pages, you look at a list — and since your journal, habits and goals are in the same system, the connections show too.

That connection is the hardest thing to produce by hand: whether your minus days coincide with poor sleep, with a recurring person or with a particular day of the week. Not after one week, but after six it typically becomes clear.

What it does not give: the seven measurements are yours to make. A minute and a half a day, and this is the one part of the whole thing that cannot be automated — because the point is precisely that YOU say what left you in what state.

The first week — starting tonight

No preparation is needed, and no tool has to be chosen. This is the whole thing.

1. Tonight: write one line — a number from minus three to plus three, and half a sentence about what happened in the second half of the day.
2. From tomorrow, for six days: the same, three times a day. If a measurement is missed, never mind — do not fill it in later, because that is memory, not measurement.
3. Next Sunday: ten minutes, three questions — the two biggest minuses, the unexpected plus, and whether the minuses cluster in time.
4. One change. Starting with the biggest minus: deletion, grouping or pairing. One, not three.

And if the end of the week shows nothing surprising? That is a result too — it means you know exactly what takes it out of you, and from then on it is not the insight that is missing but the decision. That, though, is what another article of ours is about.

Frequently asked questions

What is an energy map, and how is it different from a schedule?

A schedule shows where your day went; an energy map shows what state it left you in. It does not measure how long something took but whether you have more or less energy afterwards. That matters because often the problem is not the quantity but the composition — a few specific items take a disproportionate share.

How often should I measure?

Three times a day: once late morning, once in the afternoon, once in the evening. You will quit hourly notes on day two, and the data will be skewed anyway because measuring itself takes energy. One entry takes half a minute: a number and half a sentence.

What scale should I use?

Minus three to plus three, and measure the change, not the state. “How much energy do I have now, from zero to ten” is useless because all day it measures the time of day. The good question is: do I have more or less energy than at the previous measurement?

What is the fourth drain we tend not to notice?

The transition — not the task but the switch between tasks. It has no name, does not appear in the calendar, and cannot be recalled. If you switch between radically different kinds of work seven times a day, you are rightly exhausted in the evening while “nothing big happened”.

Why is it not the hard thing that tires me?

Because exhaustion does not depend on difficulty but on whether you had control over the situation, whether it had a close, and whether you had to play a role that is not you. That is why hard work often closes in the plus while something short and trivial closes in the minus.

What should I do with the result?

Start with one change, at the biggest minus. There are three options, in this order: deletion (plenty of things are in your day only because they got in there once), grouping (this lowers the cost of switching), and pairing with something that fills you.

What if all my entries are minuses?

Then the map is no longer about your energy budget. Continuous exhaustion and nothing filling you are signs not to be solved by organisation — our article on the signs of burnout covers this in detail, including when it is worth seeing a professional.
