This question is ambiguous. Which cognitive processes count as "thinking" and which do not? How do I know if in a given case I thought or I intuited or etc...? What if I never think before I speak but I often intuit the reactions of others? What if stopping to think(here meaning to actually deliberately go through it either in words, symbols or at least picturing it, a sudden insight or just remembering a lesson from a previous example doesn't count) would actually make things very awkward because then my attention wouldn't be where it needs to be?
Words used to refer to mental phenomenon are always very ambiguous and few people stop to think about and appreciate that.
An example of the ambiguity of the word "think". As a child when people said "you're thinking about, stop thinking" in connection with say sports I got confused. I thought I was literally supposed to have nothing on my mind. I thought "think" meant any sort of cognitive process I had any awareness of. So "focus on the ball" and "don't think" together were highly confusing. I figured that my "subconcious" or "unconscious" (wasn't sure which or what to call it) was supposed to notice the ball and it wasn't supposed to consciously register at all.
I was very shy as a kid. Otherwise I probably would've picked up on these things faster through trial-and-error interactions. It's a lot easier to get what people mean by "think" in its various manifestations as an adult especially since the subject of Sapir-Whorf theory and linguistics is one of my interests.
