Reclaiming What it Means to Be "Professional"

I recently held a webinar with a new software system that I wasn't totally comfortable with. It was time to start the webinar, and I could see that people were signed in, so I went ahead and switched it to "live" and started talking. I knew the chat function wasn't working, but I didn't know how to fix it, and while normally I like to get confirmation that people can see and hear me, I decided to just move ahead since we were recording.

So, I'm talking, sharing my slides, doing my thing...for about twenty minutes. Twenty minutes, so like, almost half of the time I've set aside for this thing.
