A lot of speech therapy is literally centered around radical acceptance. Stuttering freely. The handicap is in most cases not the reduced words per minute, it’s all the learned avoidant behavior that causes us to take less risks socially and professionally. That’s what is really holding us back. Spending all your time and frustration trying to figure out how to make it go away (it won’t, you just learn how to manage the worst parts slightly better) is way less productive than simply learning to accept it and live your life in spite of it.
