It is what you know that determine who knows you. Nothing empowers like knowledge. “To be informed is to be transformed and to be uninformed is to be deformed”. There is a difference between been informed and possessing the working knowledge of a thing.

You can have the functional knowledge of a certain application but without the working knowledge you can not make the most of it. For example; a messaging application can only be operated if you have the working knowledge of how it works. So many of us just have the knowledge of most things but we lack the working knowledge of how it works for our profiting.
