Bear in mind the simple rule, X squared to the power of two minus five over the seven point eight three times nineteen is approximately equal to the cube root of MCC squared divided by X minus a quarter of a third percent. Keep that in mind, and you can't go very far wrong.

Having little money to spend was a valuable learning experience. My schooling also shaped my work ethic because while other children were listening to the Goons, I was studying, which enabled me to go to Cambridge University.

At Cambridge, you have to kiss the vice-chancellor's fingers. But I missed out on that, 'cause I was doing a matinee. I don't want to kiss a strange man's fingers anyway.

I never pay any attention to figures.

I live in a Spanish-style hillside home in Los Angeles, California. I paid $900,000 in 1995. It's perhaps worth about $3m now. Thankfully, I paid off my mortgage before the crash because I could see it coming. I worried that I would be caught having to pay off a very high mortgage for a house I couldn't sell.

I pay taxes in three countries, but can't vote in any of them.

I'm not careful with my money at all these days. I buy people a lot of dinners!
