Although most artistic endeavors such as music, art and dancing are enhanced through the use of imagination, it can also be applied to many aspects of everyday living such as cooking, gardening, decorating, housekeeping, fashion and making love, to name a few.
Sometimes, it is stimulating to do mundane tasks in a new way by using one's imagination to be more creative. For example, I have a friend who is conservative in her political persuasion, but imaginative in how her home is organized and decorated. From the way her paintings are hung to how clothes are separated in her closet, she is extremely imaginative in how she handles her household, doing everything in fresh yet simplistic ways.
In art, imagination is delightful to behold when an artist presents material in unexpected ways that are uniquely his own. Two artists who immediately come to mind are Fernando Botero and Pablo Picasso. Botero's portly people are recognizable in his paintings, drawings and sculpture, while Picasso's cubist renderings are his own, no matter how many times his influence is apparent in the work of other artists.
I believe that we are all artists and that we all have the ability to imagine, however, I also believe that some of us choose to leave our imaginations in the conceptual stage rather than bringing it forth.
