Hey, I’m 20, and during my internship this summer, towards the end I had a conversation with my boss about my stutter, I was an construction inspector. I mentioned my stutter, and he said he just got used to and didn’t notice it anymore. Take this information with what you want, but people are genetically coded to “ignore useless information”, in my opinion, this is a good mindset to go at it. Take this with a grain of salt, I also have large self esteem issues, and it holds me back aswell. I just hope that this tidbit of information might be comforting. Goodluck!
