You can swim: the guts to speak freely
I have trained online public speaking courses almost every day of this year. One reason that people join the trainings: they feel they do not connect with the audience when a screen is in-between.
The fear is totally unfounded.
Virtually everyone connects easily through Zoom, or whatever the platform. This is obvious at the beginning of a training. When participants share what they want to get out of the day, they talk smoothly and naturally, they are being themselves, they connect.
