For me writing and filmmaking is a therapeutic process. It reflects themes that I'm going through at a time in my life.

When I'm driving I should make more of an effort with my iPod, but I'm too lazy to organise a playlist.

Red Bull are backing a spinal-injury research charity called Wings For Life, which I am an ambassador for, with a programme called Faces for Charity that will run at this year's British Grand Prix.

One of the biggest things I struggle with in life is not being present. I'm worried about my future or I'm dwelling on my past, and I'm wondering why I'm not feeling so great right now, but it's because I'm everywhere else, besides what is currently happening in front of me.

For me to train and get ready for racing, I can't just sit in the gym all the time and that's the way it is. Responsibility starts and stops with me. My main gig is grand prix driving, that's what I do and I need to keep that in the forefront of my mind.

I love directing and that's where I'm headed. That's where my head is at.

A lot of filmmaking is all about filtering out the bullshit.
