Public speaking tip of the day!: are you looking for more live public speaking opportunities where you get to speak to a live audience? Do Facebook Live!
You can do Facebook Live just with your friends and family. If you have a couple hundred friends on Facebook, which is the average number for most people on Facebook, maybe 5 people will tune in to watch you. That is pretty low pressure. The stakes are low, you will not be losing your job because of it, and it just makes you more comfortable speaking.
My recommendation is that pick a time once a week when you are giving a presentation live on Facebook. It could be you talking about your Chess Club, or about your favorite architectural designs. Whatever it is, just talking about something knowing that people can see you and ask questions will strengthen your public speaking muscles.
