Switch creative endeavors? Why? Why, when you work so hard to improve your writing, painting, photography or whatever, would you switch?
For a couple of reasons:
It's a mini-vacation, one that doesn't take you out of creative focus. A break that is refreshing and renewing and still keeps the juice flowing. Creativity is the same, no matter what you're creating.
The major benefit is creativity begets more creativity. Doing something different ramps up what you were doing before. Weird, huh? But think about it. I know that for myself, when I take photographs or make jewelry or write a film script instead of working on my novel, I get tons more inspiration for my w.i.p.! I suspect that working on something else frees up the subconscious to work on the main project.
Have you tried this? Do you have more than one creative passion? If so, what's been your experience?
