@askvinh: If you want to learn how to become a better communicator, start by becoming aware of what you like and dislike any time you see or hear someone speak. This helps you build the awareness muscle of what you perceive as good communication! Then by recording a video of yourself speaking on a topic for 5 minutes, you can now start applying these likes and dislikes to yourself to improve the way you communicate. I know recording yourself can be hard (I still cringe at myself 😵💫) but the process of reviewing and reflecting is what makes the difference between you being an average and a great speaker.
