You've got to be oblivious to other people, the push and pull of other people's opinions, the way other people measure success. It's then that you realize you are 100 percent who you are and you have to use that who-you-are 100 percent in order to create great things.

I can't understand why most people believe in medicine and don't believe in art, without questioning either.

I always try to make everyone mellow down, make sure everybody's happy. The people I have employed have always kind of stayed with us. A lot of people who come to work for you are artists in their own right. And they want to work for you because they want to pick something up.

But I think it's more that when you're young, you're invincible, you're immortal - or at least you think you are. The possibilities are limitless, you're inventing the future. Then you get older and suddenly you have a history. It's fixed. You can't change anything. I find that a bit disturbing, to be honest.

As a father, I would say I am more like a mother. I do a lot of hugging.
