You're very Rikku-like, I agree! I'm split between Thief and White Mage because you're upbeat and cheerful; you said you liked to help people and you don't like annoying people, which seems very White Mage; but on the other hand you said you're energetic and mostly confident, which makes me think Thief. I'm going to go with Thief for now, but yeah I'm a bit torn.
