Well if you believe in that, I guess more power to you... But something as starting a YouTube channel can't really be compared by pursuing a career that requires articulate and fluid speech. So I can't say that stuttering isn't part of our identity, and that's a good thing, because we at least learned how to adapt, studying body language and having more knowledge about human behavior to some degree. How ever, one is not master of his stutter if he doesn't want to stutter, if one would to be master he would be conscious of the fact why he stutters rather then being produced by our unconscious (if stuttering I's produced psychologically). How ever, one should overcome stuttering and aim for overcoming rather then to accept such terrible faith we've been pointed towards to. Rebel against it, might sound absurd but that is the point of the absurdity, one finds enjoyment in fighting with something one can't possibly win... Like sisyphus, we can't know if its possible to overcome stuttering, but we can aim it and find it meaningful, and its not a question if we can to overcome but how to fight such absurdity we've been diagnosed with, while finding pleasure in doing so.
