I would be the devil's advocate and disagree with you. There are more dangerous self help books like The Secret who took the Bible quote about praying and it will come true out of context, and many other THE 4-HOUR WORKWEEK, LAW OF ATTRACTION....
For those new to philosophy I recommend starting with Plato, Then reading his Republic especially chapter XI , then read some Descartes, Hume, Kant and then read Aristotle who is simply know as The Philosopher
