Just because it's a bad job doesn't mean I need to do it badly.

I run six-to-eight miles a day, plus weights and aerobics in the lunch hour. I also lie a lot, which keeps me thin.

I have my moments. Ever since I was a boy, I never was someone who was at ease with happiness. Too often I embrace introspection and self-doubt. I wish I could embrace the good things.

I'm not a religious man... I find I am a fan of science. I believe in science. A humility before the facts. I find that a moving and beautiful thing. And belief in the unknown I find less interesting. I find the known and the knowable interesting enough.

You hope that your teenage self would like and forgive your 50-year-old self.

I just read an 800-page history of the Scottish Enlightenment and, honestly, I may as well just start it again now, because I cannot remember a single thing. I can barely remember where Scotland is.

I am very, very aware at all times. I'm watching myself, I'm listening to myself, I'm judging myself, critiquing myself all the time, and I will know when I do something and I will immediately say, "Can I do another one, because I didn't quite get that thing," or that I wanted to do something there and it didn't quite work.
