You can be thankful for what you have but still want to achieve more at the same time, I totally get you. But to be honest: I would carefully think about your goal setting. I was just like you and wanted to completely get rid of it. I had an extended period of time with complete fluency and was really frustrated when the stutter came back (although it was just a fraction of what it ever was before). I now understand that most likely you will never completely get rid of it. Accept that you are a person who stutters and embrace the journey of becoming the best possible speaker that you can be. With a lot of hard work and building new strong habits you might reach a level where stuttering doesn't influence your life anymore (and where you can be fluent for 99% of the cases), but even then it will still be somewhere in you and can surprise you occasionaly. I would say you have different options, such as regular speech therapist, intensive speech courses or doing your own research. I myself joined an intensive speech course (McGuire Programme) and am really glad with my progress so far. If you want to do your own research books as Stutter Redefined by John Harrison, How to stop stuttering and love speaking by Lee Lovett, or Beyond Stuttering by McGuire are good. Try what works best for you and whatever direction you choose from here: keep working on it and don't give up.
