On the first day of work, I was a little scared, and I couldn't keep up with my teaching. Sometimes I didn't give you a chance to learn after studying for a long time.

Everyone will be nervous on their first day at work, because when they get to a new environment and new people, they are afraid that they can't make jokes on others. There is no need to worry about this and that all the time. Just relax and do your job. You can slow down on the first day, but you must do a good job in quality, so that you can take your time, build up your confidence and become more and more skilled.
