I don't think acceptance and working through your problems are mutually exclusive. You can accept that you have a stutter now and still work on improving/fixing it. I don't think you have to necessarily surrender and just let life be when you accept something. And when we say theres "no fix to stuttering", we mean scientifically, theres no research out there with strong evidence pointing to a specific fix. Of course there are people out there who has fixed their stuttering. Joe Biden, Steve Harvey, Emily Blunt, Ed Sheeran etc. But they could've fixed their stutters in different ways. I recall Joe Biden saying he would practice repeating words and syllables he struggle with in front of a mirror when he was a kid, akin to speech therapy. But others found their fix through changing their perspective in life, like what works for me the most is not dwelling on what people would think of me. Not being embarrassed of my stutter because I did not choose that for myself. Not making a big deal out of it etc.. And just because I'm not embarrassed of it, doesn't mean I'm proud of it, it can just something that's not a big deal. Like imagine you are flat footed, you don't have to go around telling people you are flat footed, but if someone invites you to run a marathon, you might tell them that its a struggle for you because of your flat foot. The same way I don't go around proud and letting people know I have a stutter, but whenever I have a block and it gets weird and awkward, I'm open to letting them know that I have a stutter, that way they wouldn't get weirded out. Less judgment makes it easier for me to talk fluently. But then again that's just me, I'm one sample size. There's no scientific study otherwise pointing to a definitive cure.
