Some situations are like a jiu-jitsu match where an opponent can pin you down. In a subset of these situations and unlike in a jiu-jitsu match—you can’t tap out.
Say you’re in one of these situation.
Don’t avoid the feeling provoked by this impending doom. You can’t tap out. You cant restart the match.
In such an encounter, grace might mean to keep fighting. Keep thinking. Keep struggling. Recognize your prison.
Fortune favors the prepared mind. :)
This in no way detracts from your point - unlike the Titanic, steering away from ecological disaster too late will never make things worse, it just won't be enough - but the metaphor isn't quite apt.
