Heather McGregor, alias Mrs Moneypenny, is a high-flier who owns and runs the executive search company Taylor Bennett.
She also has her own TV programme on Channel 4 about how to scrimp and save, which, though it focuses on domestic money-saving, extols principles every manager and organisation should take up.
When it comes to women who want to get ahead, Mrs Moneypenny says that self-confidence is key and "an attribute that all ambitious women need to develop".
According to research from the Institute of Leadership and Management, female managers have significantly lower self-confidence and higher self-doubt than their male counterparts. This is to their detriment, because higher levels of confidence mean you are more likely to go for a promotion, ask for a pay rise or get the recognition you deserve.
The book also makes a plea to have more women on boards. There's a pathetically low number of women directors in the UK - how many does your charity have, for example? The more women at senior level, the better off the women are in that organisation, and the better off it is as a whole.
