When the ideal solution is not available, the British find a way to make things work with what they have. Waiting for perfect conditions or perfect tools is not the approach—the approach is to devise the best workable solution from available resources, accept that it may not be elegant, and get the problem addressed. A serviceable fix implemented now is valued over a perfect solution that never materializes.
The ability to improvise under constraints—to repurpose available resources, to find creative workarounds, to make do—is genuinely admired as a problem-solving skill. The pursuit of perfection should not prevent the achievement of adequacy. What matters is that the problem gets addressed, not that the solution looks impressive.
