Courage means showing up to the rematch knowing exactly how bad the last one went.

There are two ways to go back. One needs a story in which it will probably be fine, and that story collapses the moment the first thing goes wrong. The other holds the real scoreline in mind and goes anyway, which is sturdier, because nothing left can surprise it. Knowing precisely how bad it can get and arriving regardless is the version that survives contact.

Rather than talk yourself into confidence, name the worst realistic outcome and decide you can live with it. Then play for the one or two things you have genuinely changed since.
