Add friction. Then wait a day.

Because willpower loses to one-click. Removing saved cards is the single highest-value change: it turns a two-second purchase into a deliberate act of typing sixteen digits, which is often enough for the urge to pass. Logging out, deleting the worst apps, turning off shopping notifications and unsubscribing from marketing emails do the same job — they put a speed bump where the money leaves.

More than it feels like, because impulse spending arrives in small pieces. Four small buys a week at around 12 plus one larger purchase a month works out at 326 a month and 3,917 a year — with roughly 1,175 of that going on things that end up unused. A waiting rule that stops half of it keeps almost 2,000 a year.

Most impulse wants fade within a day, so a waiting rule catches them without creating pressure. Bans build that pressure until they break — which is why no-spend months so often end on day nine and are followed by a bigger episode. The plan keeps a set amount each month you can spend on wants with no justification, because a plan with no room for enjoyment doesn't survive.

It's worth pausing if impulse spending is the problem. Splitting a payment makes the total feel smaller, several running at once are easy to lose track of, and missed payments can carry fees and in some cases affect credit records. The friction step covers how to step back from these alongside the other changes.

Then it may not be a discipline problem. Spending that follows low mood, anxiety or stress — or that comes with hiding purchases, debt you can't repay, shame afterwards, or periods of unusually high energy and little sleep — is worth taking to a doctor. Compulsive spending is a recognised difficulty and treatable, and free debt advice services exist. Nothing in this toolkit shames you for it.
