> "Reality is 100% of the time, different from our imagination"
A bit of a hyperbole:
100%? So never ever we can predict reality? I think, if we focus on the core details, we are better than always wrong, perhaps even much better.
Anxiety causes you to imagine how a scenario would play out, in detail. Flashes of things going wrong, something breaking apart and all the terrible things that a horror movie director could imagine.
