I have a theory that this is the Monty hall problem effect in practice [1]. When you blow up your life you are opening an unknown door... But after you have narrowed your options, so the outcomes are likely to be better than your status quo.
So maybe this analogy doesn't really work...
The analogy only really fails if your internal value system values predictability... Which for some people is true.
But for others who have a vague feeling of dissatisfaction then the chances are that the unknown door picked from a shortlist of options will yield better results than staying put with the option given to you via external factors
