The powerless words

To balance what I just said about the power of words, I need to point out when words become so weak that nobody will pay attention to it.
There is saying from someone: "You can get by on charm for the first 5 minutes, then you'd better know something."

So knowledge is what gives words power. If I didn't know what we can do, and how we do them, no one would listen to me, no matter how good my communication skills are.
