What does it mean to be "aware"?

In the dictionary the word aware means having or showing realization, perception, or knowledge. In health class, or any psychology, we learn Maslow's Hierarchy, the highest point on the pyramid is Transcendence, which means self actualization. An important part of this would be to have awareness and i believe that is important in any situation. It may have to do with being aware of your safety, whats around you, or aware of someone else's actions. Recently I have found it to be a helpful skill to recognize a persons body language, because it can often tell you what they may be thinking. To be aware of this is a useful way to engage in conversation and help a lot with further communication. I am someone who thinks very thought out, where i can find reasons behind everything going on around me and everything people do. This is a step towards having an awareness of my surroundings.
