I agree with the people who say there's little to do in this game compared to other titles. I mean, this isn't a shooter, rpg, animal/monster-training game, simulator, etc. It's just a little time-killer game. A very cute one at that, but yeah, if I try to play it for too much of a duration at once, I get SUPER bored.
Also, those who are saying that if the OP thinks there's not much to do in this game he or she shouldn't have gotten the game, I think you should stop and think about what you're saying. It wouldn't be unbelievable to me if this is their first AC game, heck, this is my first one! With all of the hype surrounding New Leaf, a lot of people got introduced to the series via this game. It's very... different. And I have no frame of reference to compare it to as I never played the previous games. So to me, it's just a very simple game.
I'm now awaiting other games, so this is sort of a buffer game for me as of now. I hope to still play it every couple of days or so, like I've been doing, since I don't want my villagers to just forget me or move away. I've also been very tempted to restart, but I don't know. I feel like the ultimate achievement would be to play through with the same town for an entire year. I want to experience all of the seasons and holidays with my villagers! There's still a lot to look forward to, I know, so right now the name of the game is patience.
