Sometimes my brain is more valuable than other times. But there’s an easy way to manage this. I have half-a-brain jobs. These are jobs that require only 50% of my cognitive function.

About four years ago, when I was 41 weeks pregnant with my second child, my phone rang. I sent it to voicemail because I didn’t recognise the number. A woman I'd worked with before, Fiona McBeath, had left me a message saying she'd changed jobs and was wondering if I was available to do some work for them.

My ten-year-old son asked me yesterday “why is Dad working so much more than you when you both have jobs? It doesn’t seem fair.” I told him that’s just the way it is at the moment. And this is true, but the fire of resentment is building in me, as I suspect it is in households all around the country and the world.
