After my second-to-last record 'The Greatest' I had gone on tour for a while and I didn't play an instrument for about five years. And I got kind of - it's not self-esteem or whatever or anger toward myself - but disappointed in myself that I hadn't been challenging myself to learn musically.

Wise anger is like fire from a flint: there is great ado to get it out and when it does come it is out again immediately.

I did not want to put myself on the line as an Australian playing Britain's greatest comic actor. The fans of Sellers are obsessive possessive - and aggressive. I did not want to risk their anger - or my own reputation.

If anger proceeds from a great cause it turns to fury if from a small cause it is peevishness and so is always either terrible or ridiculous.

Something my mum taught me years and years and years ago is life's just too short to carry around a great bucket-load of anger and resentment and bitterness and hatreds and all that sort of stuff.

Anger is a great force. If you control it it can be transmuted into a power which can move the whole world.

The great thing about celebrity culture is that they can't seem to stop themselves from displaying their ridiculous behaviour. I feel it's my job as a serious investigative journalist to witness all kinds of behaviour and then report back to the audience through the prism of my own anger and bitterness.

I think that Scottish people like Canadians are often misunderstood and what I like about my Scottish friends and relatives is how quickly it can go from love to anger. It's a great dynamic.

It's a joke to think that anyone is one thing. We're all such complex creatures. But if I'm going to be a poster child for anything anger's a gorgeous emotion. It gets a bad rap but it can make great changes happen.

The greatest remedy for anger is delay.
