It is necessary to practice eloquence and speech skills

The company held a technical meeting yesterday, involving a document I wrote. the boss suddenly told me to share this document with my colleagues. the result is very poor. I didn't know what I was talking about, and finally I spoke about my sweat.
Being inarticulate and introverted seems to be a common problem for most developers. In fact, I am not in front of very familiar friends, but it is also easy to talk about.
If you have any questions, you need to analyze them and overcome the difficulties. I will analyze myself first. Why do I just stamp the documents in front of many people...
1. Nervous, afraid that you can't speak well, the more nervous you are, the worse you will be. This should be a psychological obstacle and can be overcome through self-training.
2. No preparation in advance, no organization in the lecture, and the brain is in a blank state. If you know that you want to explain something in advance, you can prepare it, and the effect will be better. However, in an emergency, for example, yesterday, I thought it was necessary to overcome the tension first. If you are not nervous, you will not be confused. If you are not confused, you will not be able to talk about things and be rational.
3. Lack of speech skills, lack of understanding of the psychology of the audience, and fail to guide the audience. In this case, I think we should have a good look at the relevant materials and practice more.
No communication ProgramExcellent, it is also a stuffy gourd. In the end, I think it is a breakthrough in my mental barriers. Don't be afraid of being ugly. In fact, I have made a breakthrough in my introverted personality, one year at the school's bonfire party, I rushed to the stage and sang "heart-to-heart" in front of hundreds of people. I thought it was good, but unfortunately it was not handsome, and I was not fascinated by PL xuemei. However, the face was quite thick.
That's it.
