I learnt how to remain calm and control my emotions and it made a huge difference. I worked in a software company for almost 2 years and my job was to lead software development and handle all the technical teams. So I had to interact a lot with colleagues and sometimes clients. I don't think anybody noticed my stutter as I had a reputation for my skills. Well if you need any help just let me know. Doors are always open. We all are on the same team.
