Would you like to avoid giving the impression that you lack self-confidence and authority with your words? Avoid the next ten in a wide arc and your performance will immediately be more grounded and sovereign. Because if you think that self-doubt can only be seen in facial expressions and that it can be hidden behind an e-mail, you are deeply mistaken. And that's why you don't need to know how to read between the lines, because everything is beautifully black and white.
