Thanks a lot for the replies, everyone!
I do know where a lot of you are coming from. I'm probably not asking the right questions. There's technically nothing wrong with the bike at all. It's flawless. Heck, I've only had it for two weeks now... going on three. Nothing is preventing me from riding. I was just wondering if there was something specific that a lot of avid riders/enthusiasts upgrade on the bike immediately?
I'm going to do as a few of you suggested and continue riding each and every day that I can. I think once I familiarize myself with the bike even more than I am now, I'll be able to better determine what it is (if anything) should be upgraded beyond stock form.
