Is Creativity work?

My Tripod Productions business partner, Steve, is a creative light switch. He is able to turn it on when taking daily walks near Zilker Park and Auditorium Shores. That's where the idea for developing the audio program of his published book, A Movie A Day, was ignited. He is often inspired at the oddest moments. That is an admirable ability, in my opinion-- especially since I have been taking my own little creative journey with The Artist's Way, developed by Julia Cameron. I am working through Chapter 8 now … and enjoy the reawakening of my own creative spirit. Has anyone out there had unique moments with their creative side? Where does creativity come from? What inspires you?
