Who says it better than Winnicott?
A few years ago I was toying with writing a book called Hide and Seek, but those ideas eventually became chapter two of Keep Going:
Creativity is about connection—you must be connected to others in order to be inspired and share your own work—but it is also about disconnection. You must retreat from the world long enough to think, practice your art, and bring forth something worth sharing with others. You must play a little hide-and-seek in order to produce something worth being found.
