How can I encourage adults and children to enjoy art?
Encouraging children and adults to enjoy art comes down to one major step: getting them to understand that being a "good" artist is not necessarily a matter of natural talent or an inherent "gift," but rather the result of consistent, dedicated practice. Many people do not enjoy making art simply because they are afraid that their work will be judged or evaluated negatively, or that their work will be compared to the work of others in a derogatory light. Fear stands in the way of many potential artists, as well as the pressure to make something "beautiful."
Help your adult and child students develop good habits as artists. Instruct them to put a discipline in place to practice their craft. Ask them to work on their particular form of art for a manageable amount of time (say, fifteen minutes or so) every single day. What they draw, sculpt, sketch, or paint doesn't have to be shown to anyone; it may be kept private. In this way, they will be so consumed with practicing at a safe distance from critical eyes that they will naturally both lose their inhibitions and improve over time!
