"A lot of people get rigid as they get older because they think they should be ‘wise’. But the child in us, the source of playfulness and joy – that’s the source of all the loveliest things in life. The most creative people have this childlike facility to play. I do. But one or two of my friends think of me a little bit as ‘not grown up’. And I realise how trapped they are in the need to be grown up – which I’ve never felt."
- John Cleese, Monty python’s flying circus
