I find it some of the hardest photography and the most challenging photography I've ever done. It's a real challenge to work with the natural features and the natural light.

There's an adage that is an apt description of the new dynamic at work between brands and consumers connected through social media: People support what they help to build. But now that many brands are launching community-driven cause marketing campaigns the challenge becomes what to do next?

I suppose for me as an artist it wasn't always just about expressing my work I really wanted more than anything else to contribute in some way to the culture that I was living in. It just seemed like a challenge to move it a little bit towards the way I thought it might be interesting to go.

I think life is full of challenges and problems. I don't believe that anyone is perfect. We all make mistakes. It's not a bed of roses and you have to work real hard at it.

People are not perfect... very often the relationships that are strongest are those where people have worked through big crises but they've had to work through them. So the challenge to us is to work through that.

I like the challenge of trying different things and wondering whether it's going to work or whether I'm going to fall flat on my face.

Irony regards every simple truth as a challenge.

Truth lives in fact for the most part on a credit system. Our thoughts and beliefs pass so long as nothing challenges them just as bank-notes pass so long as nobody refuses them.

My biggest challenge is trust and really believing that trust in letting things just happen personally and professionally and trust with myself. But I'm getting better at it.

When you do a drama you are challenged to trust your inner voice much more. Because when you put a comedy in front of even a 25-person screening you know whether it's working or not. The barometer is overt.
