Hi everyone has given great advice, I’m just offering a trick that can hopefully help boost confidence. So I’m a millennial age 30+ we used ear buds like Apple air pods for example. Something that you can try, put one ear bud in your ear and play music or anything really and have one ear free to listen to someone else talk and that honestly helps me speak fluent in conversations. People don’t question it since I’m already older and accustomed to taking work calls. But you can give it a try and I hope it helps.
