Growing up, I learnt to think, 'Let's make it a big night tonight, as you never know what's going to happen next.' So now I have enough, I take too much; when I get the chance to have a fine dinner, I will. And it's had an effect on my health.

Growing up, I lived in a house without art: no picture books on the shelves, no visits to museums, no posters on the bedroom wall.

We do not need to be heroes to save the world; all we need is humility, a critical view of the commercial and political interests of those who would mislead us into wrongdoing, and a sense of wonder.

In time, we will have to recognise that it is not 'nature' that we need to protect, but ourselves, and we can only do this by abandoning the old, grandiose, profit-seeking schemes so beloved of our masters and learning to till the soil, live to scale, and live within our means.

The moment of creative impulse is what an artist gives you. You look at a Pollock, and it can't give you the tools to do a painting like that yourself, but in doing the work, Pollock shares with you the moment of creative impulse that drove him to do that work.

I don't like to get too caught up in habits because too much structure can stifle creativity. But there are a few habits that make us more productive and are healthy to work into every workweek, if not every day. I love to start the day with a workout - even just a run on the treadmill while catching up on the morning headlines.

After touring with David Bowie last year, I was inspired to look at what I wanted to do as an artist, and I realized I wanted to go back to the music I fell in love with when I was eight years old.

You think, 'You hired me because I'm a creative artist with a vision. Don't try and knock it out of me.'
