I’m a very slow thinker (2016)
I'm the same way! I have to train myself not to think when people give a casual "hey, how are you?".The book "Quiet: The Power of Introverts" has an interesting message about how introverts struggle to fit into an image of society where one must be a quick-witted extrovert in order to be successful and powerful. I think it's the same for fast vs slow thinkers. It's important to know your a slow thinker, and accept it as a strength.
