Twitter has restored my faith in humanity. I thought I'd hate it, but while there are lots of knobheads, there are even more lovely people. It delights me how witty and friendly most people are.

Life is easy greediness adds complexity

I'm not a people person. I'm not sociable. I have been and I can be, but not as a general rule.

I used to be mouthy. It was all to do with being a northerner and from Manchester, which was suddenly a big deal when I was in my 20s. When I read some of the interviews I did back then, I cringe.

You never undertake a project because you think other people will like it - because that way lies madness - but rather because you believe in it.

It's horrible to get a cameraphone shoved in your face every time you walk out the door.

I think I can be closed in. I can close this outer shell, cut myself off and be quite cold. I can cut other people off if I need to. I don't think I'm angry, though... Maybe my wife would disagree.

I'm good at being on my own. As a kid, I was always in my room alone, so I have a high threshold for it. If I'm bored, I'll read. Hanging around doesn't go well with me.

I'm incredibly proud of 'Life On Mars' and 'Doctor Who.' They're just a blast to do.

It is what we sow into people that they become

Wisdom is better than an inheritance

Most of us will do anything to avoid facing ourselves

The economics of the security world are all horribly, horribly nasty and are largely based on fear, intimidation and blackmail.

I was going to sip on a diet soda, but a little voice convinced me I needed the extra calcium from a cup of hot chocolate.

As long as I can buy records and books and maybe some clothes, I'm pretty stoked. I don't need a yacht or anything.

I don't drive because I failed eight times and never got my license.

I believe that the only important structural obstacles to world prosperity are the obsolete doctrines that clutter the minds of men.
