No, what held me back was thinking fluency was the goal, and that achieving fluency would solve all of my problems. This mindset is very dangerous, because it automatically sets you up for failure or, in the best possible case, condemns you to a life of hiding your stutter, which is downright exhausting. A better goal is to not worry about your stutter - and that has the added benefit of reducing your anxiety enormously, which in turn tends to reduce the incidence of stuttering.
