User blog comment:LiliumSnow/A Question Regarding Jaune's Non-Existing Training/@comment-63.155.149.125-20131005021237

The way I interpreted what Jaune said was that he's always wanted to be a warrior, but perhaps his father (or another member of his family) though he was god enough, and tried to squash his dreams. Which would explain his attitude. It's not pride that's driving him to refuse Pyrrha's help. It's the opposite. He has extremely low self esteem, and feels he has to fix his problem himself in order to prove to himself that he's capable.

If his family wasn't supportive of him, or actively derisive of him, then it would make sense for him to feel like he doesn't measure up, and that he has to prove he can do things himself.
