I feel like if you begin stuttering at 14 you're atypical. Maybe confidence is a key factor for you. For those like me who started at 5-6, and haven't stopped since (now 30), confidence is not the deciding factor. Telling people to have confidence is not a bad thing, but my concern is it will lead to undue frustration for anyone getting their hopes up. I've gotten my hopes up about many things, many times, and I'm sure others have too so it's not the end of the world. Glad you were able to overcome yours though.
