Habits break at the seams of your week

Ask someone why a habit collapsed and they will usually say they lost motivation. Look at the actual dates and something more specific shows up. The running stopped the week of the school holidays. The writing stopped when the project went live and evenings disappeared for a fortnight. The early starts stopped after a week away.

Habits do not decay evenly. They break at the seams of the week, the points where its shape changes, and they break there because the habit was attached to a shape rather than to an intention.

Where the seams are

Most people have four or five, and they are the same ones year after year.

• Travel, including a single night away.
• School holidays, or anything else that moves the morning.
• A period of unusual work intensity with a known end date.
• Illness, yours or somebody you look after.
• Any week containing a move, a visitor, or a deadline that eats an evening.

Between those, a habit that has survived a month will generally keep going without much attention. That is the useful asymmetry here. You do not need a system for ordinary Tuesdays. You need one for roughly eight to twelve weeks a year, and you can name most of them in January.

The rule that survives a seam

A habit written as a time and a place will break the moment the time or the place moves. A habit written as a trigger and a minimum will not.

Run for forty minutes at seven in the morning is a shape. It cannot survive a week where seven in the morning belongs to somebody else. After I put the coffee on, I do the smallest version of this that still counts is a trigger and a minimum, and it survives almost anything, because the coffee happens in a hotel room too.

The minimum matters more than people expect. It has to be small enough to be embarrassing. Ten minutes. Two hundred words. One phone call. The purpose of the minimum is not the ten minutes, it is that the chain does not break, and an unbroken chain at reduced volume restarts effortlessly while a broken one requires the whole decision again.

Plan the seam in advance, not in it

The decision about what happens to your habit during a difficult fortnight should be made in a calm week, in writing, before that fortnight arrives. In the middle of it, every option looks like failure and the easiest one is to stop entirely and resume afterwards, which is the version that does not resume.

In a one to one engagement this usually happens around the third or fourth session, once the first seam has already caused a problem. The commitment for that fortnight becomes: write down what the minimum version looks like during the three weeks in August, and put it somewhere you will see it in August. That is a genuinely dull commitment and it is one of the most reliably useful ones in the whole method.

When a habit should be allowed to end

Not every collapse is a failure of structure. Some habits are attached to a goal that is no longer real, and they persist out of momentum long after the reason went. If a habit keeps breaking at seams that are not particularly difficult, it is worth asking whether the underlying goal survived the last six months, rather than adding more scaffolding to something you have quietly stopped wanting.

That question is uncomfortable and it is much easier to ask out loud, on a schedule, than alone. Weeks three and four of the group program are largely this, worked through against each participant's actual week rather than in the abstract.
