Genius is the high end of the dimension of creativity.
Creativity in turn is the expression (effect, result, projection) of awareness. Awareness is what the individual experiences inside one’s mind (the experience of experience itself; the being aware of the fact that one or anything exists), while creativity is what others perceive when observing that individual. Awareness and creativity are the inner and outer aspects of the same thing. One’s creativity is a measure of one’s awareness. A non-creative person is not aware; A genius is the most aware of all.
I like this definition of genius.
