Every living, breathing human being has the potential to be creative. We are, simply, quite a creative species. All people can be creative but those who are recognized as being creative have an awareness that others don't. Creative people seem to be able to tune in more to their thought patterns and glean great ideas. People who do not use their creative potential don't know how to do this or aren't even aware it is possible.
Creative people can start thinking about something, then forget it.
Meanwhile, their brains are still thinking about it. There are many components that influence the creativity of individuals. The reasons why some people are more creative, however, are many. Without the abilities needed to do the creative act, it is highly unlikely the individual will do the act. Just because a person has the ability to do something, however, does not necessarily mean that the person will do it.
