Query: Disappointing

In a word "Disaster"! This book was terrible! I agree with the reviewers that stated TG was preaching at us. I skipped over all the boring lectures and didn't miss a thing! TG needs to get back on track or give up writing. My recommendation is that you borrow this book from a friend or get it from a library. Do not spend money on this book!
