I'd definately say the game has barely even begun to begin until you have a job at 75. After that things change a lot. You really have the means to do a lot of things. Crafting is much easier when you have a 75 job to help you earn enough to invest in crafts. You can level other jobs with full knowledge of how they work and what gear to use. You can afford the gear much more easily. You can run around and do countless quests without as much worry about your safety.


Anyway... you truly don't begin until you are at the end of the game.
