On the phone, I have some good advice for you. But you have to practice very often. I pick up the phone, breathe into my lungs quickly and with concentration. Immediately exhale and in that time I say the name of my company and my name. We have 4 seconds for this. A stutterer can speak with his air for a maximum of 4 seconds. A person who does not stutter, on the other hand, can speak with his air for 8 seconds.I can't plan everything else because I don't know the questions yet. But I will take my time for the answers. The advantage is that the other caller does not see your blocks, he only hears silence during this time. Thanks for your tip with Magnesium!
