Drinking a ton of styles can be difficult if you are buying cases of expensive beers only to realize you don't care for them. There are quite a few stores around me in Maryland (and even some in PA, which is crazy if you know the byzantine alcohol laws PA has) that allow you to buy individual bottles and create your own 6 pack.
Also, try to find some beer festivals or homebrew festivals to get yourself introduced to more beer styles/beer culture. Brew pubs are good places to learn too. The brewer is almost always around at the smaller ones, and they love talking about beer, giving you samples, and just basically trying to educate you.
Search bjcp for homebrew style guidelines and the archetype beers they are based off of.
Reading about the history of beer and beer styles is kinda cool for me, Tasting Beer by Randy Mosher is a good place to start (the last halve, just going over styles, gets a little drawn out, but still a good read). You'll learn not only about beer, but wine and food and flavors in general.
also, let your beer sit a little longer, the changes are amazing, one week it tastes terrible, the next it's amazing. Just brew another one while you wait.
