For me:
1) I would not act like a damn child.
2) Seriously train everyday to become more powerful.
3) When I'm fighting, I would fight seriously instead of using kagebunshin all the time. I would use the kyubi power.
3) I would fight back to that bitch Sakura if she treats me with that annoying way like punching my head and shit.
4) And I would definitely date Hinata since she likes Naruto that much.
