Unless one has been there, no book can make one fully understand. To claim knowledge of something without having the experience to back it up, it is difficult to be sincere with people. The only real learning that takes place anywhere is when ones ears are open and ones mouth is closed. The people who have to remember what they say are usually in what I call "dress rehearsal" at all times. Their true selves would not fit into the category they see as what is best for them. They know they have to play roles. To a certain extent, we all play roles in life. But when it comes to making money, people will say and do anything to achieve their ends... no matter who suffers. Take poverty, for example. Unless one has been flat busted, homeless, and/or addicted and scared, no book has enough words for anybody to know unless they too have been in that place.
