Words are often thought of as a neutral agent, you know, they simply live to serve us. But i have found that words are far more causative than that. They don't just sit idly by as we use them. So for example, if we don't have sufficient vocabulary, our very thinking will be limited. We can choose never to say things simply because other people tell us to. Words create meaning from our past, help us better understand the present and help us design the future. If you want to design a life that really matters, you have to learn how to use words in a way that really matters.
