This is a very good Question and one that for artist is important to speak out to yourself and others from time to time.
I have found keeping my central theme and motivational philosophy around my art helps me to continue to be excited about creating new work on at least a weekly basis. I have a profound love of family and family gatherings. The image of hand made whimsical dishes (pottery) full of nourishing food prepared by loving hands being passed around a big outdoor table as family sits together and interacts with discussion and laughter about life, faith, work, family, politic, and may other topics is what drives my creative spirit. I love to bring whimsy, color, texture and surprise to my functional art pottery work that sparks conversation and joy of use.
