Here's the thing about play that the serious-faced approach to life tends to miss: it works. Not as a performance. Not as a technique. But genuine, absorbed, uninhibited play - the kind where you forget to monitor yourself, where you're not thinking about how you look, where time does something strange and you surface surprised to find an hour has passed - that state is where some of the most important human experiences happen. Insight. Connection. Creativity. Healing.
