My column The Creative Pulse in the January/February issue of Cloth Paper Scissors is all about the benefits of stepping outside your comfort zone.
The following ideas are just a few that I have included in the article:
-Crack open a supply that you've never used.
-Take a class in a technique that's outside your wheelhouse.
-Work on a collaborative project with other artists.
-Add another layer to a piece you are satisfied with but know could be better.
-Usually use a paintbrush? Use your hands instead.
