Short story: Naruto operates on passion, willpower and drive; his nemesis operates on rage and drive. Normalliy drive is represented under willpower, but there is some difference. Some are adept at resisting otheres power or some effect. Whilst some are more prone to driving forward against all odds. While the result CAN be the same, thus all falling under the description of willpower, I wonder if perhaps this could be distinguished via a trait. Perhaps in a similar manner to the SAN vs will trait ideas. Some kind of negative to will but a bonus oriented towards momentum or attack?
