"I don't accept that improvement has stopped coming towards me. Even if it will stop coming towards me, it's because improvement never even came to me anymore, while I always practiced at my best. That's not a stagnation that is supposed to happen, only fools would think that way."
NM request for this cute emotional instrumental music from Heroes of Might and Magic IV. It's not from anime yet it has one of the qualities you've been asking for!
