When I sing for myself, I sing in a more free, athletic way. When I face an audience, there is always some fear that makes me put the brakes on a bit.
I never think about gifts. It's enough to have my family present.
Because, in opera, I have to sing for people that are very far from me, instead of, when I sing a song, I try to imagine to sing like in an ear of a child.
I've been to almost every country in the world, and the most frustrating thing for me has been that my schedule has always been so busy that there's so little time before and after performances to explore where I'm visiting.
