Query: A flawed but important book

It took me two attempts to finish this book and I am glad I did.The book is somewhat disorganized and muddled. I gave up on it the first time because it was a little too preachy and the initial description of the author's suffering and frequent crying was a little surpising since he just told us Vietnam finally gave his life a purpose.But then I gave it a second try. After learning later in the book more of his experience in vietnam, I had a better understanding of his pain. I realized what I'd been reading was a vivid account of his post traumatic stress disorder. This book is important and powerful because it shows a way the author found after 20 years of pure misery to alleviate his pain and suffering . Anyone who's troubled or depressed or plain just stressed out can benefit from his messages.
