Query: Attn: Artists & Intellectuals. This is a good book.

Do not mind the stars. The book is worth purchasing. 5 stars would mean that this is the last book you buy. I am a student on an endless quest for higher learning, excellence, creativity, intelligence, and so forth. I HIGHLY RECOMMEND this book to all students, teachers, and those in search of inspiration and hope of manifesting your hidden potential. My word of caution is to understand Leonardo da Vinci for who he was and what he pursued. If you too pursue truth, then follow the principles of Curiosita, Dimostrazione and so forth. Do not treat this text as a Bible. Understand the principles that helped Leonardo achieve his goal.
