You might find some encouragement from the story of King George VI, who spoke with a stutter. If you haven’t seen the movie The King’s Speech, I highly recommend it.
Winston Churchill also had a speech impediment, and yet is remembered for his speeches to parliament.
I recognize that these were people of privilege and you probably aren’t, so that makes things even more difficult. But I do believe that everyone can be useful and a blessing to those around them, even while dealing with a stutter.
It’s not a matter of education. It’s morality. This nation has sold its soul for the Dow.
