very true, its better not knowing what you are missing, in this case id just hold off until you are 20 or so to start reading up. That way you dont have a few years to wonder about all the possible things you could do now. If you honestly believe you can go about learning on this subject without being tempted to do it, than buy the book and learn all you can so you know exactly what you are doing before you ever touch the stuff. Knowledge is power.
