I could see a bit of Thief and even Soldier in your application, but in the end I think I am leaning more towards White Mage. Your positive traits remind me a lot of many thief characters like Zidane and Vaan and this is probably the reason why I considered thief for you, but your either/or section and your weakness remind me of Aerith, she is extroverted but not overly so, cheerful most of the time, modest, can act on impulse sometimes. After reading your applicaton I think you would be a great white mage and I can associate many of your positive and negative traits with white mage characters.
