There is something mysterious about creativity. We can describe it, admire it, strive for it and experience it, but we can never understand just how or why a certain innovative idea springs up at a particular time in the mind of a particular individual. Indeed, most people never expect to understand or master that process. Let's hope we do not, for our world would be far more dreary if we ever fully harnessed the creative process and learned to produce results only on schedule or on demand.
