Constance Hall on the best piece of advice she ever received.

When it comes to authentic voices in Australia, few resonate as powerfully as Constance Hall's.

As a bestselling author, entrepreneur, and social media phenomenon with over 1.8 million followers, Constance built her community by being honest about everything from motherhood to mental health to body image.

But for someone who regularly dispenses wisdom to millions of women, I wanted to know: what is the best piece of advice she's ever received?

So I asked her.

I sat down with Constance on this week's episode of This Glorious Mess and she was her usual candid self. As best friends for some 37 years, our conversation — as they always tend to do — flowed into deeper territory, too.

When asked about the most impactful advice she's ever received, Constance didn't hesitate to credit her Auntie Lisa.

"She always gives me fantastic advice," Constance told Mamamia.

"And I think as women, especially during divorce and during baby-making years, or when you're thinking about divorcing, we have this fundamental fear of losing our security, and that drives so many of our decisions, and they're not always great decisions.

"Even women who I know whose husbands and their net worth together is 10 million, will still be saying to me, 'I can't leave him, because I'll be on the streets.' Like, this is just a (worry) that women have."

The fear of the unknown is also hard.

"You wish you could go back and say to your younger self, 'It's going to be okay because you're always okay'. There has been so many times in life where you think, 'No, this time, I'm not going to be okay.' But voila, you are," she said.

"Auntie Lisa said to me, 'Women need to stop thinking of money as our security' because this is where the fear comes from. She goes, 'Your bank might go bankrupt tomorrow, your house might burn down while the insurance company goes bankrupt, these things happen to people, and you will end up with nothing'. She said, 'The only security that you will ever have is other women'. It's me. It's you. It's the people that you are fully connected with, because as well as your mum, we will never let you not be okay. And nothing could ever stop that, no amount of global disasters could stop us from doing that for you."

This reframing of security as relationships rather than assets and a spouse has stayed with Constance.

"I've always thought about that, because, what a beautiful way of looking at life," she reflected.

"The people that you love and that love you are your security."

Constance explained how this perspective can be transformative during major life transitions.

"It's really difficult when you're marrying and you're divorcing and you're having babies. It's really hard to make the right decision if you're constantly focused on your own security," she said.

"It keeps you in the potato-picking kind of role. You never get to dream bigger because you're always freaking out that, 'Well, no, I have to play the game because I gotta keep the roof over the head'."
