My acceptance of my own slow thinking has terrified me no end my whole career: terrified of interviews, on the spot tests and of selling (especially when dismissals are based on incorrect or flawed understanding). I always go home to brutalise myself with "Ah, I should have said this in response". Too late!

I've always attributed my slowness to my breathing - or more precisely, my incorrect method of breathing. I mostly breathe from the chest instead of, as recommended, from below the rib cage, and more from the belly.
