The anticipation is the thing that kills me as well but I've gotten better as I've brewed. Hey, if you think waiting is hard now wait until you get into lagering. I have two beers right now that are chill aging on their 6 month its so hard to wait but they are ready now thankfully. Another suggestion for your extract brewing, when I started my first batch was an American wheat and I went on and really tried a wide range from a cream ale to as dark as a stout and everything between. It was good because it opened my palate further, and gave a bunch of knowledge of different types of malts, specialty malts, sugars and hops it was great experience.
