There are people who now drive motorways without a thought who once had to pull into a service station to breathe. Nothing about motorways changed.
What changed is that they built a record. Each trip added a data point the nervous system could not easily argue with, and after enough of them the old forecast simply stopped being credible.
Courage isn't a mood you summon beforehand. It's the residue of things already survived, which is why the second difficult conversation is easier than the first, and the tenth barely registers.
You are adding to that file today, whether or not it feels like progress from inside.
