My suggestion: keep at it, for a couple more days at least.
I also wondered the same thing when I first started (my first AC experience) - and I would've probably sought reassurance from GAF as well had I not been banned at the time.
But once you've got the hang of the basics and got your approval rating to 100% (shouldn't take more than 2 days), suddenly you have hundreds of things to do and it's hard to keep up - in truth, the game is about time management and some of that time is devoted to inventory management - but quickly enough you'll have all these goals to achieve (some set by the game, some set by yourself along the way), and you pray that you don't forget anything.
The game can be played with skill, with ingenuity, clarity of mind and a good memory, but of course, the beauty is that the game doesn't have to be played that way if you'd prefer not to think about it too much.
