I agree tasting is of first importance, and paying attention to what you taste (not just wine, but everything) is essential. But I respectfully disagree that reading is unnecessary, or even detrimental. I'm not talking about specific tasting notes--it is certainly best to form your own opinions, but it really helps to read a little, so you can figure out your way around your local wine shop to know a little about what you are buying. If you just grab three random bottles of "Bordeaux" in the $15 range, take them home and pop them open without understanding where they fit in the context of the region, you might come to the tragic conclusion that you don't like Bordeaux, or French wine in general. Ditto for almost all wine regions in the world. A few basic books can really open your eyes to what's out there and give you a compass to navigate the wine world, or at least your local wine shops, on your own terms.
I hope you enjoy your exploration.
