Elizabeth Day is the author of How To Fail: Everything I've Ever Learned From Things Going Wrong.
It gives advice on how to own your failures, and why doing so is the key to success.
The book is based on her podcast, 'How To Fail with Elizabeth Day, which is now in its fourth season and features high-profile people discussing their failures.
The podcast came about after the end of a relationship, when Elizabeth began having conversations with female friends about heartbreak: "I began to wonder what it would be like to open up this conversation about vulnerability into a more public arena."
When reflecting on her own failures, she realised that she had learned more from moments of crisis than from the things that went well.
Elizabeth says her truest definition of failure is "when something doesn't go according to plan, you're thrown a curveball by life, and you don't learn from it."
She feels that failure should be used as an opportunity to grow and build up emotional resilience: "We should attack the idea that we should feel any kind of shame over it."
As for her definition of success, Elizabeth disagrees with the modern-day tendency to treat happiness as the ultimate goal.
"Success is acknowledging that life will throw you unexpected things, but often these things are gifts in a strange form."
"It's being able to observe the process rather than feeling overwhelmed by it."
