I'm not sure acceptance is something I 'achieved'. It's more something I do when things are less than ideal. How I got to the point of being able to do that in regards to stuttering was a bunch of things. Realising that stuttering wasn't the only thing in my life and that other things were more deserving of my attention. Learning about my other traits rather than focusing on speech. Realising that most people are more concerned with themselves than with how I speak. Putting things into perspective - there are worse afflictions. When you give it less attention, it has less power, then it's easier to focus on other aspects of life. Then when it does rear its ugly head, acknowledge it happened, acknowledge whatever you felt about it, figure out if you can do things differently next time to improve, then forget it and move on.
