Do you think OVERTHINKING is the power of doing because you're thinking? Or saying because you're verbally processing your thoughts?

And do you think OVERTHINKING is a started fact, as in we as humans know when someone is starting to over think something? Or do you think it is a matter of personal opinion that you, yourself make because you think someone exceeded the boundaries and limits of your conversation, and you think they're over thinking it?

Oh irony, I'm over thinking rn. XD
