"No art takes places without inspiration. Every artist also needs effective knowledge of his or her tools (e.g., does a certain brush function well with a particular kind of paint?). What's more, artists need effective techniques for using those tools. Likewise, to express ourselves skillfully with maximum efficiency and minimum effort, we need to investigate the most effective ways of using the mind and body since, in the end, they are the only "tools" we truly possess in life."
