I 'm not an artist that paints or creates sculpture. I have to label everything I draw. I don't compose intelligible music. And my writing is mostly informative, but exercise is paramount in helping me solve the problems I encounter as a student, trainer, and writer. It helps me explore my imagination and create solutions.
Imagination is more important than knowledge.
Knowledge is limited. Imagination circles the world. It will allow brilliant ideas to flow in and out. We all have the ability to create within us, and exercise is one good way to nurture that.
