The term “imposter syndrome” was coined by researchers Pauline Clance and Suzanne Imes in a 1978 paper. It describes the feeling of not being worthy, or adequate enough, for a particular role: as if you don’t deserve to be there.

Imposter syndrome is more prevalent among women. A telling statistic from the firm Hewlett Packard shows that men apply for a job when they meet only 60% of the qualifications, but women apply only if they meet 100% of them.

Even from the point of hiring, then, women have a tendency to underestimate their potential to learn and thrive in any given role.

In talking openly about imposter syndrome, Willis joins an impressive roster of high-achieving women who have addressed the issue, from politician Sophie Walker to Michelle Obama.

“I had to overcome the question ‘am I good enough?’” Obama writes, in her memoirs, Becoming. “It’s dogged me for most of my life. Many women and young girls walk around with that question in their minds.

“I overcame that question the same way I do everything – with hard work. I decided to put my head down and let my work speak for itself […] It takes time and maturity and successes under your belt to realise that you’re good enough.”
