Your personality as the prime minister feeds through to what you emphasise, and what you don't, how you'll handle a situation - whether you've got the combination of intelligence or instincts to adapt and to make good decisions.

I was really fascinated by politics. It always has been part of my view that politics really is a calling or you wouldn't go into it, because it's demanding and potentially has a toll on you and your family.

I want to leave New Zealand in better shape than I found it. I know the job of prime minister is not forever and I'm going to do the best I can every day to make that difference.

I guess I'm reasonably confident in all honesty. But I definitely don't think I'm arrogant. I'm pretty down to earth, I mean I'm genuinely down to earth.
