You can live your life two ways: You can use your language to manipulate. You can use it as a tool to get what you want. But the problem with that is that it assumes you know what you want, and that you're right. And that's a problem, because there's lots of things you don't know, and if you get what you want you may find that (A.) You didn't really want it, and (B.) that you're not the person that started the journey towards that. That happens a lot to people, especially when they use their language in a manipulative way.
