Mind over stutter. Reminds me of a friend who also stutters and he stutters openly but i can see it just doesn't fase him and he carries on. That approach or out look on your stutter helped you overcome it cuz you didn't give in to ' more effort and forced speech ' to overcome the block. You just gracefully acknowledge the block and let it pass eventually without a fight. William Perry describes this to. Its called something like a valsava maneuver which in turn aggravates us to stutter and block even more. Alot of us ( me differently included ) panic and we in turn try to fight the block. I got to work on this mindset or outlook that you do.
