Feeling overwhelmed? Check if your list fits your week.

Planning for the worst case is common advice, and the thesis study tested it. The students were asked how long the thesis would take “if everything went as poorly as it possibly could”. They said 48.6 days. It still took 55.5.

Fewer than half, 48.7%, finished by their own worst-case date (Buehler and colleagues, 1994).

What did work, in the same paper, was the past. In a fourth study, the habit of guessing too low disappeared for students who first recalled how similar assignments had gone and then linked those memories to the task in front of them. Recalling the past was not enough on its own. Connecting it to the new task was.

For a week, the past is easy to find: it is last week. How many hours did last week’s list take, against what you guessed? That ratio is a better buffer than any worst case.

1. Put hours on every item. A rough number is fine. Without one, the list cannot be added up, and a list nobody has added up always feels bigger or smaller than it is.
2. Give each item a time, not just a line. In a series of experiments, goals that people had left unfinished kept popping into their minds while they worked on something else (Masicampo and Baumeister, 2011). Making a specific plan for when and how to do it stopped that, even before any of the work was done.
3. Cut until it fits, with your buffer. If the list with your buffer is bigger than the free hours, something moves to next week, gets smaller, or goes to someone else. Deciding on Sunday is easier than finding out on Thursday night.
4. Keep some hours empty. A week planned to the last hour has nowhere for an overrun to go, and nowhere for rest. If the list fills every free hour, it is already over.

If you still feel overwhelmed when the list fits, the list may not be the cause. See the section on talking to someone below.

A good way to run this test counts your real hours from what you already write or say about your day. Then last week’s list has a true number next to it, with no timer to remember. Most journaling apps stop at how the week felt. The word “overwhelmed” is in there. The long days that caused it are not.

One app built for this is Think in Numbers, a smart journaling app with time tracking built in.

You write or say your day in your own words, as it happens or all at once. The app reads what you wrote and counts the hours that went to each part of it: work, sleep, meals, chores, your phone, and the time you never mentioned (shown as unaccounted). Then it shows those hours over days and weeks. To-dos and a weekly plan sit beside the hours, so the week you planned and the week you had are on the same screen.

The 80% line is ours, not a research finding: high enough to mean the plan was real, low enough to allow a bad day. The test runs three weeks because the first week sets your buffer. Weeks two and three show whether a plan built on that number holds.

Here is a deadline week from one example person, a made-up office worker whose hours were counted from how they described each day.

In their third week, this person had a proposal due on Wednesday night. On Sunday they spent 1h on the plan. On Tuesday and Wednesday they worked 12h 30m each, back on the laptop late at night. Their sleep on the night before Wednesday came to 5h 45m.

Then they sent it, slept in on Saturday, and the next week was the lightest of the four: 45h 15m of work against 53h 30m.

Sometimes the list fits and the feeling stays. The NIMH, a US government research institute, advises that if you are struggling to cope, or your symptoms won’t go away, it may be time to talk to a professional. A doctor is a good place to start.
