My biggest hurdle was replying to emails by myself since my English wasn't fluent. I always needed my colleagues to help proofread them, which led to a fear of replying to emails because I was scared of making typos or grammatical errors. Encouraged by a friend, I decided to attend the Innovative Communication Methods using ChatGPT course, hoping it would improve my email and report writing. After the course, I was able to reply to emails by myself, which saved a lot of time. As a result, my colleagues and manager praised me for my improved English and overall work performance.
