In my opinion, I think that if Naruto achieved the rank of Rokudaimed, then Konoha would be stepping into a new era completely. He'd end up being one of those Hokages that people in the other great shinobi nations would have to take their hat off too.
With this in mind, Naruto would probably let this go to his head a little bit at first. However, this is where Sakura would step in. She'd stop by when she's not busy with running the hospital and what not, and she'd be that person who gives him reassurance that he's doing his job right as Hokage. Oh, she'd whack him across the head a few times
, but it only be because she loves him so...
As the saying goes, 'Behind every great man is a woman rolling her eyes at him.' Yes, he would be a great Hokage, no doubt, but I also think that Naruto would need to be straightened up every now and then when he gets in over his head. Basically, if people had trouble convincing Naruto to do something as Hokage, they would go to plan B: Ask Sakura to convince him, lol
