In the DMG for 4th Edition, the first chapter goes into a breakdown of different styles of play and what each player enjoys. You might be well served to browse that chapter at an RPG store and see if you find yourself nodding in agreement with any of the play styles presented.
I think this is a really good idea.
Those above who are saying that there is no wrong way to play are correct. You should just enjoy whatever parts of the game you enjoy and don't worry about it too much. But I would encourage you to be somewhat self aware as you do this. When you are having a really good time, first tell the GM what a great time you had after the session. Then maybe talk a bit about what made that session so fun for you.
This is incredibly valuable information to both you and the GM. With that information you can express to the GM what sorts of things you enjoy most about gaming and the GM can in turn try to be sure to include those things.
This concept becomes doubly important when you are GMing because including elements in your games that you know the players will enjoy on a frequent and consistent basis is far superior to accidentally including them once in a while.
