Every day I go through the same crisis. I sit there and nothing comes. But I win the struggle, because every day, I write. And this crisis refreshes me. But it can be terrible, too – I become depressed if no ideas are there. It’s always difficult at the beginning of a piece, when nothing is there, and at the end, when I don’t know how to finish. And it’s the same whether it’s a two-hour opera or a little waltz.
