Query: This book changed my life

No fooling. It changed my life.I was introduced to the wonderful writings of Robert Heinlein at the age of 16 by a buddy at military school who suggested this book to me. It's hardcore conservative politics and disregard of the 'pseudo-sciences' of sociology and pop-psychology changed me from being a wanna-be hippie to a free-thinking man.The story it's self is entertaining (please do not confuse this with the movie of the same name. The similarities end there, no mater how much they robbed from this fantastic book). It's quite amazing to follow young Juan Rico as we watch him grow from spoiled high school senior to 2nd lieutenant. The real joy, however, is Heinlein's explanations of why conservatism works.I recommend this book to anyone of any age.
