I also had a moderare-severe stutter as a kid which I eventually and gradually grew out of as I exited my teens and into my 20's. I can't identify any thing in particular that I did or that happened that led to my stutter fading away. It was embarrassing and mortifying going through school with it and no amount of pathology or exercises seemed to help. What's funny is in my adult life I've compeltely 180'd to the point where I've built a professional sales career throughout my adulthood which revolves around sales presentations, cold calling over the phone, and regular sales coaching and pitching/training/addressing large groups of staff and clients. I get the odd block here and there nowadays, but nothing beyond a quick block that I can generally roll through and continue past. Having said that, I think it's a little overreaching to suggest that people suffering from a heavy stutter need to simply "man up" and/or stop whining and try and push past it. I don't know all of the science and pathology behind successful treatment, but I am willing to believe that some of us simply get lucky and something about our physiology allows us to eventually repair whatever faulty wiring was causing the original stutter. Severe stutterers will always have my full sympathy and patience, particularly when I find myself actively engaging with them. Stuttering to me is (was) as debilitating as a learning disability, non-hygiene based body odour issues, or even some physical deformities. And to brush it off simply because you are one of the lucky souls who found success in somehow growing out of it is a little unfair in my opinion. That's not to say that you didn't put a lot of energy and focus into actively trying to deal with and "cure" your own stutter, and maybe you have some insight that others may benefit from. I'm sure you're making this post in an effort to empower people who stutter to work towards a solution, and as a sales professional and somebody who is generally competitive and team-oriented by nature I can definitely appreciate how you feel. But I also feel that telling anybody who's still having to deal with a moderate to severe stutter on a daily basis that they're making excuses and that they're not allowed to be visibly upset about their condition is a little short-sighted.
