I didnt overcome it (nobody does), but pretty damn close. I had a mid to heavy stutter groing up (varied depending on sleep and social setting). As I went through highschool, college and early career, yeah it was tough sometimes, but I perservered. Speech therapy + learning about yourself (emotional and anxiety triggers). To get better at talking, you need a hollistic approach (mind, body) but you also need to practice difficult situations. There is no other way IMO to decrease anxiety related to speech. Get out there, face your fears, there is no other way. Talk, practice, take notes, record yourself speaking (yeah, I know...) and YOU WILL IMPROVE. I'm 43 now, I have a great career where I manage a small team of 4. I do presentations in front of the Executive Committee, I MCed an event last year in front of 100 people. I do stutter here and there but its very mild now. My DMs are open. Happy to chat.
