Many writers have been known to pursue multiple creative outlets. Steven King plays the guitar in a band, and within our Master's Artist community I happen to know that Jeanne dances and has a great eye for photography. Simon writes music, Mike is pursuing comedy, Donna sings, and Mary loves to cook - all different forms of creativity. We may have one primary outlet (writing) but in my experience creativity is unable to be contained in any singular pursuit. It just sort of leaks out - all over the place at times.
Creativity can be messy, but it's a good kind of messy.
