The big message is that we need to reimagine and re-engineer how we work - what does work mean and how do we measure what's good? The second thing we need to reimagine is our relationships - who does what and why? One of the biggest things that has helped me and my husband is coming up with a common set of standards about what it takes to run our house, what is a fair way to divide tasks, and how are we going to keep each other accountable?

If you had the perception that you are very stressed out then your grey matter was fully 20 per cent smaller in volume than people who did not have that same feeling. This is the grey matter in your prefrontal cortex: It controls thinking, learning, planning, decision-making. That matters because when we are feeling more stressed, that is when we are at our most vulnerable in our inability to think our way out of it.

What if not just women, but both men and women, worked smart, more flexible schedules? What if the workplace itself was more fluid than the rigid and narrow ladder to success of the ideal worker? And what if both men and women became responsible for raising children and managing the home, sharing work, love, and play? Could everyone then live whole lives?

I think that was probably one of the biggest revelations, is leisure is really in the eyes of the beholder...

A gift, like a good friend drawing a personal road map out of the crazy busy swirl of our overloaded lives.

I have trashed the to-do list. To help my brain...

I was afraid that I would find out that I didn't work hard, that I wasn't a very good mother. I was feeling so inadequate in everything I did. I was afraid that I was going to come out being this crazy, disorganized, neurotic person. So it was revelatory that I worked more than 50 hours a week and I still spent a tonne of time with my kids. It was like, "Why do I feel one way when the reality is so different?"
