I remember watching Mel Gibson on some show once, and he was being asked about his belief in the afterlife. Gibson said: 'Well, I can't believe this is all there is'. And I thought: 'Wait a minute. You're Mel Gibson. You have millions of dollars. You're a great-looking chap with every conceivable blessing that could be bestowed upon a man. And that's not good enough ?'

Death and disaster are at our shoulders every second of our lives, trying to get at us. Missing, a lot of the time. A lot of miles on the motorway without a front wheel blow-out. A lot of viruses that slither through our bodies without snagging. A lot of pianos that fall a minute after we've passed. Or a month, it makes no difference. So unless we're going to get down on our knees and give thanks every time disaster misses, it makes no sense to moan when it strikes.

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.

One of the principal goals in my life has been to avoid embarrassing my children by doing the job I do. I hope I've managed to do that, and I hope that, with the job I'm in now, they are, if not proud, at least unembarrassed by it. I must say, my three are most agreeable children, who do nothing but delight me.

Now, my mom always said two wrongs don't make a right. But she never said anything about four wrongs, and that always left me confused.

I know a lot of people think therapy is about sitting around staring at your own navel - but it's staring at your own navel with a goal. And the goal is to one day to see the world in a better way and treat your loved ones with more kindness and have more to give.

My dad gave me my first bike at 16. I soon fell off and was in a wheelchair for weeks. I haven't fallen since.
