The first time I heard this it needed a little explaining as my first reaction was "what do you mean my stuttering doesn't hurt me with the experience that I had". But my speech therapist and now good friend explained to me "the struggle you are having is you are doing everything to try not to stutter, that's what is hurting you". What if, we can get to the stage of just stuttering with less struggle. He explained your fluency doesn't do you any good by saying, " Think about the times when you appeared fluent, did it take much effort and did you use any of your tricks and avoidance behaviours to appear fluent?. Do you think this did you any good?.
