Hey man, I'm 24 years old and I have to call customers over the phone almost every hour of the day for work. I'm not going to lie, it's tough calling someone and listening to the ring while my chest is super tight due to the anxiety of stuttering. It always takes me 4-5 tries to say "This is \_\_\_\_\_ from \_\_\_\_\_\_\_\_\_\_." You eventually just learn to accept it and start to care less about what people think. Like I said, I'm 24 years old. I do not have a college degree, nor do I work in sales, but I'm pulling 80k/yr just from salary. I'm also about to get married and have two cute kitties. Yes, cats lol. Don't worry, I want some kids too, but that's for later. I always thought the stutter would be an obstacle to success/happy life. My point is that it gets better and the stutter isn't going to stop you from accomplishing your goals. Just keep doing what you're doing and everything will work itself out.
