Some people do adopt entire belief systems out of a book or a group but that is rarer since it means they are uncomfortable with the whole way they were living. Very unhappy place to be.
Most people tend to evolve worldviews over time, a bit here and a bit there, and don't switch them in oe fell swoop. Those self-help book reviews--"It changed my entire life!"? They better be hype!
Unless of course the book in question is Ayn Rand - Atlas Shrugged.
