Being a teacher definitely has its perks.

I get to see every student that comes through the Academy. Some of them; I think to myself; will certainly go on to become great ninja, serving Konoha wonderfully.

Some of them I see become like I was. Those who can't get attention other ways seek it out through pranks and humor. Those are the ones I try to reach out to the most. I try to give them something to work for. After all, why would they bother wasting any effort on improving if there was no one around to appreciate it?
