ok so the why I definately agree! :D
Just probably the nr 5.
As I am a guilty overthinker and stand up for it, I have to say that alot parts of it can actually be quite useful for the solution. I guess the why question you referring to occurs there is more in a phase when one did not acept the status quo yet.
Which brings me to one thing I have asked myself the whole time when reading the post: how? :-)
Well there are a lot of people who complicate things by overthinking. If overthinking works for you, then why not?? There is always an exception. :)))
