Gizmo's quote fits well here:
With that app you have a decent chance of being accepted but serious admins are boring and annoying. You can still do your job without being uptight.
When I was first accepted here, I went into some sort of serious mode, no idea why. Just because one is, or is not an admin, does not mean they have to change who they are. Sure, there might be a couple more things you'll have to do here and there, but overall no change in the person is needed. After reading the application, and having personal experience with your adminship, I recommend you, as Zuki.
