Doodling

"Every artist dips his brush in his own soul,
and paints his own nature into his pictures."

Henry Ward Beecher

It is well established that much of our creative expression is birthed in the unconscious mind. To use creative expression and solutions in your everyday life, it is necessary to dip into the unconscious at will. Doodling is one way of doing this.
Doodling allows the unconscious to render in symbolic expression. Symbols have universal as well as personal meaning. When you are stuck for an answer to a problem or looking for creative innovation, the technique of doodling will unleash the hidden symbolic powers of the unconscious mind.
