Many of us are almost as afraid of standing up and talking in front of a room full of people as getting attacked by a shark or murdered by a stranger.
While the odds are slim to none, the angst around public speaking is very real. About a quarter of Americans report having a fear of public speaking. If you assumed that simply doing all your talking remotely via Zoom would remove the fear, the last year would tell you otherwise. For some, the intimacy of Zoom actually makes the whole experience that much more unnerving.
