Generate a full detail guide on the importance of 'play' for creativity. The guide should be fun and permission-giving. It must include detailed sections on: 1. The psychology of why play lowers the stakes and reduces fear of failure. 2. The difference between 'practice' and 'play.' 3. A list of 10 practical exercises to introduce play into any creative process (e.g., 'Use your non-dominant hand,' 'Write in a genre you've never tried'). 4. How to create a low-pressure 'creative sandbox' for experimentation. Please include a supportive disclaimer.
