After 25 years in high-pressure corporate leadership, Penelope Barr has reached a breaking point many professionals know too well: she was succeeding at work, but exhausted by life.
Now, the former executive is turning decades of experience across global organisations, including NAB, ANZ and Allens-Linklaters, into a powerful new message: high performance doesn't start with hustle—it starts with sleep.
Her debut book, Win the Night to Win the Day – Sleep Well. Work Better. Live Best. (Hardie Grant), launching 26 May 2026, offers a science-backed framework for leaders and busy individuals to optimise energy, productivity and wellbeing—one night at a time.
"Want to do better work, in less time, with more joy and less stress? Start by sleeping like it's your job. Sleep isn't self-care. It's your greatest performance tool," Barr says.
From corporate success to personal cost Barr built an impressive career spanning executive, board and advisory roles, but the demands came at a steep price. Long hours—often 14 to 16-hour days—impacted her health, relationships and, most critically, her sleep.
Five years ago, while juggling senior roles and parenting, she recognised that the "hero mentality" around overwork wasn't just unsustainable—it was actively undermining performance.
In response, she redesigned her life around what she calls the 6:3:3 model—a year structured into seasons of work, creativity and play—and began experimenting with how sleep could become a strategic advantage.
A data-driven case for sleep Barr's book combines personal insights with extensive research, including a survey of more than 250 people's real-world sleep experiences and interviews with global experts in sleep, productivity and behavioural science.
Among them:
- Dr Jenny Brockis, Lifestyle Medicine expert, emphasises that sleep is her number one non-negotiable for functioning well and shares strategies to ensure a good night's sleep is within reach if we prioritise our wellbeing.
- Alison Gardiner, CEO of SleepStation UK, emphasises behaviour change aligned with personal goals
- Omar Zenhom, CEO of The $100 MBA, highlights the need for evolution to achieve meaningful progress
The urgency of Barr's message is backed by compelling data:
- 30–45% of the global population reports troubled sleep
- Poor sleep leads to the loss of 11 productive days per year
- Sleep deprivation contributes to an estimated $44 billion in lost economic output
- Well-rested teams are 15% more productive, more collaborative and better at problem-solving
- Optimal sleepers experience 30% greater presence and 26% less productivity loss
Practical tools for modern life Win the Night to Win the Day moves beyond theory, offering actionable systems designed for real-world demands.
Key concepts include:
- Transition Rituals – structured practices to move effectively between work, home and rest
- The 10PM Club – a practical program to help readers consistently prepare for quality sleep
- A step-by-step framework for shifting from "always-on" living to intentionally energised days
Win the Night to Win the Day by Penelope Barr is released May 26, 2026.
