Well, there's a lot of ways how あなた can define creativity but for me creativity means an action mix with feelings cuz it depens how do あなた feel at the moment, when あなた create something for example あなた can 表示する creativity in your choises for example in the clothes あなた wear,your hair style,in the way あなた write,etc. creativity it's something beautiful that comes with imagination and it depends how is your imagination to create something.
My definition of creativity is anything really, ranging from a doodle on a page to a well described plot outline for a novel. Creativity to あなた may not be others imagination of creativity, but in the long run, it's still creativity.
My definition of creativity:it leaves it totally open and imaginative to one's mind, ハート, 心 and soul and what あなた put down on paper brings that out...it can be whatever あなた create and everything is a tool for creativity :)
