Honestly, I am weary of those self-help books. The same hammering breathe this way, do this, do that, don't do this, etc. ~ it all feels rather restrictive for me. I am a student of literature and while searching for literary works with stuttering characters, all I found were self-help books. I understand their motive, but imo they're also negating in a certain sense because the way they are written is backhanded. More than self-help books, positivity has helped me. I hope that the personal sense of positivity helps everyone in the long run!
