Panic narrows life quietly. Rarely by decision — by a series of individually sensible declines, until there’s a list of places that aren’t really options any more.

A ladder is that list, ordered, turned back into things you can do.

Step one: write down what you’ve been avoiding. Everything, including the things you’d say you don’t avoid so much as prefer not to. Motorways, supermarkets, cinemas, lifts, queues, being far from home, being alone in the house, trains, the dentist, exercise that raises your heart rate.

Step two: rate each one 0–10 for how much fear you feel thinking about it now. The tested version starts real-world practice at items rated 3 or higher⁹ — a starting point that’s genuinely uncomfortable rather than trivial.

Step three, and this is the one people get wrong: make each rung concrete. The research is unusually insistent, with its own example: ‘Each practice is to be delineated as concretely as possible (e.g., driving past two exits only, rather than driving until too panicky to go on).’⁹

Read that example closely, because it’s doing two things at once. Driving until too panicky to go on isn’t just vague — it makes panic the finish line. It guarantees the trip ends at the worst moment, and it teaches that the escape is what ended it. Two exits ends where you said it would, whatever the fear did in between.

The standard: the practice should be defined so ‘there is no uncertainty about whether the practice was conducted as planned’, so you know ‘exactly what the practice will entail (e.g., “I will walk around inside of the mall for 10 minutes by myself”).’⁹

• Not go to the supermarket → ten minutes inside, on my own, mid-afternoon.
• Not try the motorway → on at junction 12, off at 13.
• Not stay in the queue → join the longest queue and stay to the till.

Step four: note what changes the difficulty. The research asks for the moderators explicitly — ‘distance, being accompanied or being alone, the time of day, proximity to an exit, and so forth.’⁹ These are what turn one situation into six rungs, which is what you want: the supermarket alone at 5pm and the supermarket with your partner at 8am are not the same rung, and pretending they are is how people conclude they’ve plateaued.

Two mistakes make a ladder useless. The first is building it entirely out of nines and tens, because those are the ones that feel like the real problem. A ladder with nothing on the bottom is a wall. The second is the opposite — filling it with things you can already do, which produces a satisfying run of ticks and no new information.

The useful ones sit around three to five: genuinely uncomfortable, plausibly doable this week.

One thing a ladder is not: a schedule. It doesn’t have to be climbed in order or finished. It’s a map of the ground panic has taken, laid out so you can take some of it back at whatever pace is real.
