Why it comes back when things are going well

People expect the danger to be a bad week — a crisis, a rejection, something obviously hard. Those do happen. But the more common shape is quieter, and it goes like this:

Three good weeks. You feel fine. The plan starts to look like something you built for a version of yourself that no longer exists. The phone comes back to the bedroom, because obviously it is not a problem any more. Then an ordinary bad evening arrives and there is nothing in place.

Feeling better is a risk state

This is the part worth sitting with, because it is counterintuitive: feeling recovered is itself one of the higher-risk conditions. Not because confidence is bad, but because it is what makes people quietly dismantle whatever was carrying them.

The things that were working were mostly not effort. They were arrangements — the phone charging in another room, going to bed earlier, having one sentence written down. Arrangements keep working when you forget about them. That is their entire advantage, and it is also why they are so easy to drop without noticing.

The four-part sequence

Ask people to reconstruct a lapse afterwards and you get a strikingly consistent chain:

• a stretch of feeling fine
• one or two arrangements quietly abandoned
• an ordinary trigger — tired, bored, alone, late
• nothing in place to meet it

Not one of those four steps is dramatic. That is exactly why they are hard to see coming.

What to do about it

Keep one thing alive even when you are certain you do not need it. Especially then. One arrangement — the phone one, if you only keep one — costs nothing on a good week and is the entire difference on a bad one.

And treat a run of good weeks as information rather than a verdict. It tells you the arrangements are working. It does not tell you they can be removed.
