I exactly want to know the same thing . I have excellent thought process and can come with answers in a second but due to the fact that i stutter i can't say them properly or i dont speak those thoughts entirely . I can become an excellent speaker and anything related to speaking if and only i didn't have this stutter . My friends who go for debates and Lot other speaking competitions , i know i have better pronounciation of words , better control over vocabulary but it all gets messed up when i stutter . Preparing is pointless participation is pointless because it all boils down to the fluency and speed . But i control over none because i stutter . Life would be in a different place if i could just not stutter
