Does this sound like the set of challenges you might be facing?

• I keep playing out this decision in my head as if there’s just one way it goes
• A scenario laid out as a vivid story grips me, but the moment I’d try to say it plainly
• I’ve lived inside this scenario so long that every piece feels obvious to me
• I’m bracing for and planning around the absolute worst version of how this goes, and it hasn’t even crossed my mind that there’s a whole range of ordinary, fine outcomes that are far likelier than the one I keep rehearsing.
• My plan only works if a whole chain of things all go right
