I was disappointed when I didn't get the top job at the FCA [Financial Conduct Authority]. I really wanted it and I thought I'd do a good job. I struggled with the decision to go, but people were telling me it's good to leave on a high before anything goes wrong.
I did think very hard about going to a bank. But it was all about making money for yourself, and cultural change doesn't seem to be happening quite yet. I couldn't see myself spilling the beans on the dark arts of a regulator.
When we were reforming the FSA's enforcement division, my team spoke candidly about how dreadful it was going to feel making people redundant. It would make me in particular unpopular, but it was the right thing to do. I think women are more sharing of their vulnerabilities as leaders.
