“We're taught Lord Acton's axiom: all power corrupts, absolute power corrupts absolutely. I believed that when I started these books, but I don't believe it's always true any more. Power doesn't always corrupt. Power can cleanse. What I believe is always true about power is that power always reveals.”

“I'm not obsessed by how I look or with being reed thin, but I do think that as a woman in my 50s, I have 40 years ahead. Looking after yourself goes hand in hand with looking good.”
