I am torn between White Mage and a Thief for you but in the end I am going with the latter on mostly because you sound fun, you're energetic, between modest and confident (they aren't as confident as for example soldiers but now as modest and white mages for example). You're extroverted without being too much, you're a quick thinker that is something I associate with that job class as well. You seem to prefer magic though which made me a bit unsure at point but overall I think thief fits you a bit better than White Mage.

(lol@potions, I so agree. I never use them, especially in ffxiii. I bought so many just for the sake of having them when needed and never used it).
