Query: This book truly has something for everyone.

To pay for the book on the first day read the "Special Situations". Do those when you see them. The rest of the book will make you a better trader for all those other times. Some of you may be put off by the piano metaphors, but the key (sorry!)is that when you see the patterns over and over again, you'll know what to do without thinking overmuch.
