Free play by Stephen Nachmanovitch

From Amazon review

"Free Play begins with the parable of a young flute player who is challenged by a new instrument. He masters this flute, plays it perfectly but his teacher will only comment, 'something lacking.' The flute player must master himself and learn to play without fear of loss or promise of gain, must play freely."

"Let Go - this is the central message of the book. Letting go of our preconceived notions can improve our sense of autonomy, and help us play freely the game of life. Like a god. On one inspired moment after reading this book, earlier this year, I let go of this great book. So it won't any longer be a crutch I hold on to in every moment of difficulty. I have recommended this book to all my friends."

"A feel for the deep insides of creativity, no matter what path you walk in life. Life can be lived as art, and this book shows you how. Every page a blessing."

"constantly would have to rest the book on my lap, gaze up through my ceiling and just kinda let my mind wander. his use of language is extremely clear and imaginative. i would even get goose bumps after certain paragraphs, especially when he talked about the audience and the performers melting into a cohesive organism."
