People who have the tendency to or the habit of jumping to conclusions often call and categorise themselves as ‘Over-Thinkers‘. I am sorry to break it to you lovely people, but, you are not Over-thinkers; you are actually ‘Under-thinkers‘.
Over-thinking barely has to do with jumping to conclusions without collecting all the sufficient facts of the situation and without considering all the necessary facets of that situation/event. Over-thinkers, in fact, re-consider all the facts and facets of anything despite having readily available conclusions, in front of them, drawn by someone else.
Once upon a time I was this guy, living in a parallel universe, who wanted to live in another universe-in another world, And here I am, a human being, who still feels weird and awkward amongst other human beings.
