what everyone said, dailies, story and sidequest, you can also level a gatherer to 50 to get treasure maps, and a crafter to get gil, even if its slow you can get tomes doing some fates, treasure hunts, and daily to get some gear and complete the story quests, also the "chalenge log" is coming in 2.2, this could add some fun to open world, and don't forget to level your choco.

Just don't listen these ppl saying this game is not for you, they have no idea, glad they don't work for SE.
