I agree to this. It changed my life too. I blocked on 50% of my words so I didn't speak much. Now I have a leader position at my company and really enjoy hold meetings, talking with friends, joking and discussing stuff. This is not so unbelievable as it may sound. Your brain is amazing and simply said, you just need to build new and the right "connections" in your brain. I see it as constructing roads that conveys fluency. The roads will only be good and will hold if they are built in the "right way". There are probably many right ways, but Lee explains his right way and it works if you do what he says. At least it worked for me. Sadly, many stutterers seem to be very concinved that nothing can be done to stuttering and instead of starting to work on it, they complain and doubt methods that has been proven to work for many. This works if they approach it with an open mind, devote some hours daily to work on it and continue to do that for a while. I hope what I have written here will help someone.
