As I have become a man, I have realised the importance of self dignity. In life it doesn't matter how rich we are, how successful we are, how loved we are. If we lack self dignity all of those things are meaningless. Having a stutter is an attack on our dignity but it's so very important to not let that define us. Define your own self worth, based on your good qualities and your intentions and dignity will follow. I like the Jewish teaching on this matter
