The thing to remember is that the work comes first, and not to get distracted by anything else. If you keep focused on the work, everything else will fall into place. That's my mantra now.
Brain surgery is a fairly aggressive process. There's a lot to get through. There's the beautiful, delicate shaving first, which is really lovely. There's a wonderful ceremony of putting all the covers on, so only the little bit you're operating on is revealed. But once they make the incision and tear the skin back, the drill comes out.
In my life, I have made the occasional catastrophic choice, and it's just a case of moving on and learning from it.
My best friends are still the ones I first attached myself to when I went to school because, all of a sudden, I was leaving the rather pampered and occasionally very annoying world of having three older sisters to go to a male-dominated world.
If I get to the end of my life, and people say, 'He was in 'Cold Feet,' well, I was, and it was great. I thought the fourth series wasn't great. I thought there were weak episodes throughout. Overall, I thought it was a good show, it had an impact, it dealt with a lot of issues, and it was a great part.
We have to get behind the scientists and push for a dementia breakthrough. It could be that we fear dementia out of a sense of hopelessness, but there is hope, and it rests in the hands of our scientists.
My preference is for good writing. It doesn't matter if it's for film or TV. Whatever. It starts with the writing. Even though I've had problems with writers, it doesn't matter how great of an actor you are. If the writing is bad, you're going to struggle.
It's a complicated relationship with the place one grows up in, particularly if it's Northern Ireland.
I went to India with UNICEF in connection with Manchester United to raise money for children's education.
When I was growing up, Belfast City Hall was surrounded by security, and we had no access to it. But now, people come in and out of it all the time. On a nice day, office workers and students sit on the lawn outside and have lunch. It's great to see how Northern Ireland has changed. To be part of that is fantastic.
Ours was a very progressive Protestant family, but my parents were God-loving rather than God-fearing. We went to church, and I still go with my mum and dad when I return home - it's a family thing. I played flute in my dad's marching band, but I had an integrated upbringing. We had a lot of Catholic friends.
My mother taught me what it is to have a sense of humour; my dad, who was a headmaster, everything you need to know about hard work. My dad is the most decent man you could come across.
Brain surgeons are dealing with the very last thread of life, and they have to be very confident, but I think they tend to remember their failures rather than their successes, and that must be very hard. Who do you share that failure with? That's why their personal lives are often disastrous.
Belfast is a city which, while not forgetting its past, is living comfortably with its present and looking forward to its future.
