And now you have children’s skin care products.

That was me with two young rashy children; I found myself constantly using Go-To products on their skin. And I was like, “there’s got to be a cheaper way to do this because this is not economical.” So we launched Gro-To late last year in the United States and Australia. It’s four products for babies and kids. The whole genesis was you want skin care you can trust for yourself; well, you probably want that for your kids as well. The design is meant to look like toys and meant to fit in the kids’ world, rather than baby skin care that is either pharmacy-looking or has tiny baby ducks on it. My 5-year-old son doesn’t want tiny baby ducks on his bubble bath.

Your social media audience is a big part of the Go-To business. How do you approach it?

It feels ludicrous to have a free billboard to talk about your work, to go “I’ve put a lot of work into this book, I hope you enjoy it, here’s why I wrote it.” To have that platform is bonkers. People have opted in; they want to hear from you. It’s a huge privilege. I never mess with that trust.

How do you manage your time with all of the different things you do?

I just launched my children’s book in the United States a few weeks ago. It’s been my greatest book success, which I’m trying not to be offended by. I have a new picture book coming out this year in Australia and I’m just about to start writing fiction again. I have a nanny who helps me three days a week, because if I didn’t have those three days to work I couldn’t do any of this. My husband and I are a good team as well. I don’t have an answer. I’m scattered and I get anxious and I get stressed like everybody. The best thing that I can do is compartmentalize. At the moment I’m traveling and doing podcasts and interviews, and as an introvert that’s really draining. I have to come home and recuperate because it really takes it out of me. I can do it, most introverts can do it, but they just need to be in their soft clothes and watch “Goop Lab” for awhile to come back down.

What advice do you give to young women?

There’s never been a better time for entrepreneurs. There’s no barrier to entry. No idea is a bad idea. The market is thrilled with newness and novelty and innovation. You’ve got to make something that you want or where you know there is a gap. Don’t do a version of something that already exists, but have a really strong purpose and give people something to connect with. People want that connection.
