I value creativity very highly. We as a family do as well. We regularly do creative activities, and I try to find little things that help us to become more creative. Most of all, I love to help other people see that everyone is creative and to bring out their inner creativity.
One of the best things I've done is to clear off the decorative items from the coffee table and instead cover it with a collection of things like colored pencils, washi tape, glue sticks, scissors, and Sharpie markers. We have people over all the time, and for the last four months we've invited the people who visit and sit on our couches to grab some of the art supplies and to make. Everyone does, eventually. Even the ones who say, "I can't draw!" My kids are more prone to draw or sketch or cut up paper and construct something because they have access to the materials at all times.
It's amazing what can happen when the television isn't the center of your living space!
