Being aware of who you are, what you're like, and what you're capable of is what self-perception entails. It's also called objective self-awareness. The more aware you are of yourself, the better able you are to judge what actions will serve you and what won't. You can only act on that knowledge though, can't simply will yourself into objectivity. Self-perception is one of many types of perception. Other types include: Sense Perception - What someone sees with their eyes. A sense perception is always experienced as direct experience. A flower's color, for example, is never inferred from how it looks relative to other things or seen against a background scene. The flower itself is the only thing that exists, and nothing else does. We see it, feel it, smell it, taste it, and hear it with our senses directly, without any additional information from our minds. Sense perceptions are either positive or negative. If you see red then there is indeed a red flower. If you see black then there is indeed a black flower. Sense perceptions are unique to each person because they depend on which of your senses is most sensitive to certain colors or shapes.
