I constantly make lists and itineraries and then can't stick to any of them.

I went to a very academic school that actually - when I got to the point of wanting to pursue acting, they just had no idea how to do that, because all of their contacts were very academic.

David Tennant is a massive fan, and grew up dreaming he would be the Doctor Who one day. So I did feel, when I first got the job, "Right, now I've got to do loads of research into absolutely everything Doctor Who." But that's not possible to do in a short space of time. So my knowledge has been growing and developing as I've been doing it, and that's been fine. That's been appreciated by the fans, and the executives never expect me to be brushed up on absolutely everything.

My own style is one of not much effort.

I swing between procrastination and being really thorough so either way things aren't getting done quickly.

I used to be absolutely addicted to the gym and I do still love it.

I appreciate individualism.
