Being Hokage sure is a troublesome job... lol... Just think, after having fun being a regular ninja running around and stuff, you become Hokage and you get 24/7 homework.
Hmmm..... I think I'll continue fighting as a regular ninja.
Naruto is still young, I believe if we ever get to see him older, we will see a more mature side to him. Of course, he will still probably spy on girls like Jiraiya, but ultimately he will be a fine ninja who can finally come up with tactics and such.
