I’ve stuttered my whole life.. my dad has stuttered his whole life, so it’s genetic. I do have a very mild stutter but I still hate the feeling. Part of the reason I stopped going to college was because of a speech class requirement. I’ve worked in retail/customer service for 13+ years. It definitely hasn’t gotten any easier with my communications. I’m 30 years old now. Practice and relaxation techniques seem to help me. What works for you guys?
