There is no cure, only control/comfort. But when you have people like Bruce Willis, Sam Jackson, Joe Biden, etc... who have accomplished so much despite having a stutter, i think it's safe to say you can life a full life with it. The problem has a strong genetic base that we arent sure of yet, so it's not something we can just eradicate. In my opinion, the best way to deal with it is to learn to accept it and become comfortable with it. That doesn't mean you dont have to stop trying to improve your fluency, but learning to become comfortable with it I think will make life much easier and more enjoyable. you likely wont be as stressed and as a result will likely be more fluent.
