I think it means if you force people to root for you, they won't and you wont be a real leader, like if you become Hokage and expect people to like you just because of that then you fail, but if you gain peoples support then they will want you to be a leader. Or something.
Naruto was an outcast, but maybe if he had become a kage then people might still have disliked him, and he couldn't expect people to like him just cus he got the title, but he became ackowledged first and that made it possible for him to be a Kage or somethin.
Like Danzo maybe he expected people to support him just cus he was the leader instead of gaining support first or somtg.f...
