Passion to me is when you come back to some activity weither you plan to or not, e.g. you think about a programming problem out of the blue while in the shower or walking the dog. The things you are passionate about are always there in the back of your mind, presenting themselves when they wish. So passion is an attitude or state of mind regarding an activity.

Creativity on the other hand is when you come up in an idea or a solution to a problem. When you let out the stream of thoughts regarding a given topic, unfiltered by rational thinking. So creativity is the process of getting rid of your prejudices and looking a topic from different angles.

I guess they are both very different kind of concepts.

Creativity can be a passion, see artists, musicians. But also the most un-creative activity, e.g. sorting stamps, can be a passion.
