* Discovering a new idea or theory that my Ne can play with and integrate.
* Certain kinds of music.
* Figuring out a puzzle or problem that had been vexing me.
* Helping someone that both needs and genuinely appreciates it.
* Occasionally finding myself as the center of attention when I'm feeling particularly goofy. (It's always accidental though - I just get caught up in the moment.)
* A good story - whether that be in a book, TV show, or movie.
