A patch kit is confidence prepared to include an ordinary failure.

Carrying a repair kit is not pessimism but a particular kind of confidence. It says you expect to get where you are going and you also expect a puncture to be possible, and holding both is what lets you set off without worrying. Preparing for small failures is what makes ambition calm. Whoever travels without a kit is not braver, only less able to continue.

Before the next thing you attempt, ask what the ordinary failure is and prepare for that one alone. A spare, a fallback, a phone number. Then stop planning and go.
