First off stop thinking like that. YOU are holding yourself back no one else is. I'm 43 and I've stuttered all my life. I was told I wouldn't be anything. I served over 15 years in the Army 12 of that as a frontline leader and deployed to a combat zone. I also served over 21 years as a first responder. I served in every role including law enforcement, firefighter, EMT and search and rescue. YOU can do anything you want to do. YOU have to want it. F*CK everyone else. Do like I did and use the haters as fuel to prove them wrong. Keep your head up. God gave you this for a reason. Be the reason little kids who stutter have hope they can do things too.
