A repair postponed repeatedly becomes a plan to let failure choose the timing.

Putting off a repair is not neutral; it is a decision about when the problem will finally be dealt with. Postpone it long enough and the thing chooses for you, usually on a weekend, usually when it is most expensive and least convenient. The delay felt like saving money and was really trading a scheduled cost for an unscheduled one. Nobody would choose that arrangement out loud, and plenty of us choose it by drifting.

Pick the repair you have been avoiding and book it for a date you choose. If it cannot be afforded yet, deciding what the plan is when it fails is the next best thing.
