I don't see why the Op is getting a bunch of grief from the community. Is this really how a bunch of people are going to treat someone who seems realitively new to this game and is asking for help. I have seen a few suggestions, which is nice. This game is obviously not good at keeping people's attention...that should signal a red flag to the community at large.

Anywho, Op, to answer your question, other than grinding to get your character up to do the side quests, there is the main story line and I believe company quests (which I think one needs to be 20+? correct me if I am wrong). You could hunt NM's, and maybe join a very active LS if you have the time to do runs on Ifrit? Other than that, I don't think there isn't much to do. The dev's are doing their best to try and fix this game for it's users. The best thing that I can offer is maybe just to take a break until next year when it's supposed to be a completely different game. I've stopped playing myself and just log in occasionally so I can take part in discussion and ask questions. I don't want to get to far into FFXIV and it's current play style when it's going to be drastically different in a year. Sorry it's not to your liking, many didn't like it either for obvious reasons, but hopefully it will be considered "release worthy" by end of next year that it will draw back a big community for us to play in together
