If you are curious about whether you are aware of something, consider the example of addition(+). If you can do it as easily and well as addition, it means that you know it. If not, you are deluding yourself that you know it.
It is so important to knowing something properly. That is because if I know it right, I can avoid ruining myself as well as other people, at least for that matter. Furthermore, I can make myself and others better.
