I stopped believing in God when I realised it was just dog backwards.
If you think about it, g-o-d, d-o-g, it's like an anagram but a backwards one.
And then, after that, I stopped worrying about stuff. You only get one go round I reckon, when you're dead you're dead, so you can spend your time thinking about how things haven't gone perfect, or you can just get on with it, have a laugh and that. That's what I do, I'm pretty happy
