I'm a songwriter, and I understand artistic licence. We can embellish, go on little journeys and explore our inner selves. It can be quite self-indulgent.

I feel increasingly like age is very irrelevant. Quite often, cynicism is confused with wisdom, and my scorn is confused with a knowing, which I don't have.

I get up, go and get a coffee, and go do the crossword - I'm loyal to one particular paper, the 'Guardian' - and that's my idea of a perfect morning.

I've been quite fascinated by the relative insignificance of human existence, the shortness of life. We might as well be a letter in a word in a sentence on a page in a book in a library in a city in one country in this enormous universe! And that kind of fear and insignificance has kept me awake at night.

What we really need to do is get in tune with our inner selves. We've gotten way out of whack with our hunger cues. Is it hunger, is it thirst, am I eating because I'm upset or depressed, am I eating because it's there?

By reshaping or decorating our outer selves, we express our inner sense of self: 'I like that' becomes 'I'm like that.'
