Defiance is a form of optimism.
Like this: I refuse to acknowledge that. I don’t agree with your assessment. I resist the temptation to declare this a failure.
Acceptance is equally optimistic: Well, I guess it’s on me then.
The two come together well in the following principle:
There will always be a countermove, always be an escape or a way through. And just because you can’t see it right now, doesn’t mean that it isn’t there.
Defy and Trust. And you’ll never get stuck.
