I can't stand stage mothers. It doesn't work. You definitely feel that with the new generation of pop stars right now they've all managed to work it out for themselves.

There's an expression in life: "You can only make one first impression." And that first impression has to be spectacular. So, I wait, and let people see it when it's ready to go. It's not a set rule, but I think it's the better way of working. People will agree with you because of your track record, but you want people to like it because it's good, not because you found it.

I have always hated celebrities lecturing people on politics. So forgive me. But I am passionate about this country. I am equally passionate about the potential of the people who live here.
