Mages learn their first abilities really quickly so make a black and white mage. Once they learn level 3 black/white magic, change to another job class, as you can't use level four magics for a very long time yet. Definitley make a warrior, the two handed ability will never stop being useful. Monks are useful very early on but they dont equip weapons so they cant benefit from extra attack power that weapons provide. Where you are now, and for a while, no decent weapons will be available so monks will be useful. Red mages are useful at the very begginning and at the very end, but for the chunk inm the middle they will be quite useless and boring. Red mages can use level 3 black and white magic which is useful until you get level four black magic. But a red mage will still be learning that job for almost the first 70% of the game (unless you power level somewhere to stock up on ability points.)

I guess you don't have all the available jobs yet, when you get them, Master hunter. Oh and regularly use your blue mage to learn available blue magic. Obviously blue magic is useless when you first equip it, but it becomes one the best jobs as soon as you start learning magic (blue magic=enemy skill incase your unfamiliar)
