1. If you want to talk (or sing, act, etc.), you have to breathe. And if you want to do these things calmly, you'll need to breathe diaphragmatically. This won't always come naturally, and you'll probably need to practice. You might think you already know everything there is to know about breathing, and if you're a professional singer you probably do. But everybody else, be sure to take a look at the breathing material.
