You can’t use up creativity.
The more you use, the more you have.
Creativity is a gift that we must exercise on a daily basis. We can’t let it get lazy and fat. Before you know it your creativity weighs over 500 pounds and can’t get out of bed.
30/30 and other daily writing exercises help you to keep your creativity moving. Photo-a-day exercises help. However, sometimes you have to simply come up with the regimen that works best for you. Set aside to exercise in your creative method of choice. Just like some prefer yoga to cardio, others prefer drawing to writing. Find your own niche and go wild in it.
