Robert Pirsig, author of Zen and the Art of Motorcycle Maintenance:
This is an unusually intense, packed, thought-through book on the most difficult subject in the world: mystic creativity.
A review from Amazon:
I love this book. I have read this highly readable book more than 25 times in the last five years. So much that I took its message to heart, as I will specify below. The book suggests inspiring stories, tips, and lessons for making yourself more flexible at the core. 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.
