The One Thing Successful Women Refuse to Admit Is Slowing Them Down
Every month, something slows successful women down and most of them have built an impressive system for pretending it isn’t happening. You’ve optimised your calendar, your offers, and your morning routine. But one week derails everything, and you’ve been calling it a bad week instead of what it actually is.
I used to do the same thing. Then I fainted face-first on the floor of a Kohl’s, and my nervous system made its point impossible to ignore.
When Successful Women Push Too Far
I was standing in a checkout line. Nothing dramatic, just waiting to pay. Then, slowly and all at once, it started. I got really hot. My hearing went strange, like being underwater. I knew something was wrong.
But I didn’t want to lose my spot in line.
By the time I accepted what was happening, it was already too late. I went down face-first, chin on the floor. I woke up to an ambulance being called, the fire department showing up, and a circle of concerned strangers staring down at me.
Then came the mortifying part: explaining to a group of grown men that it was the first day of my period.
Everyone laughed. I laughed too. But here is what I was not laughing about: I knew my first day is always brutal. I usually do not leave the house. I broke my own rule because I thought I would be fine, and my body said loudly, publicly, and with a bruised chin, no, you won’t.
How Successful Women Mask What Is Slowing Them Down
Before that day in Kohl’s, I had tried everything. Changing my diet, stretching every night, taking iron daily, researching supplements, and tracking symptoms in apps. I told myself I was being proactive. In reality, I was finding more sophisticated ways to push through.
Every strategy was designed to make symptoms manageable enough to keep operating the same way, rather than questioning whether operating the same way every single day of the month made sense. That is what successful women do better than anyone. We optimise around the problem instead of addressing it.
We are so good at functioning under pressure that we have confused masking symptoms with managing them. Moreover, we have been so well rewarded for pushing through that stopping, even for one day, feels like a character flaw.
It is not. But more on that in a moment.
What Your Nervous System Is Doing During Your Period
What happened in Kohl’s was not just a bad period. It was a textbook example of what happens when you push your nervous system past its capacity.
On the first day of your period, estrogen and progesterone both drop sharply. That hormonal crash directly affects your autonomic nervous system, the part of your body that manages blood pressure, heart rate, and circulation. Additionally, prostaglandins (the compounds that cause cramping) can trigger vasodilation, meaning blood vessels widen and blood pressure drops.
When that drop is sudden enough, your body redirects blood away from your brain to protect your core. The result is fainting. This is not weakness. This is your nervous system responding exactly as designed. The problem was not my body’s response. The problem was that I pushed into a situation my nervous system had no capacity left to handle.
I bruised my chin and cut my cheek. In the grand scheme of things, I was okay. But I could have been a lot worse, and the scarier truth is that most successful women are doing a slower, quieter version of the same thing every single month.
You cannot outperform a dysregulated nervous system. You cannot think your way through it or hustle past it.
Why Pushing Through Is Not Ambition
Successful women have been told, both explicitly and implicitly, that pushing through is a virtue. The ability to show up regardless of how you feel is framed as what separates serious women from soft ones.
However, when you override your body’s signals during your cycle, you spend capacity you do not have. As a result, you borrow from the days ahead. The decision-making, creativity, and leadership presence you need to grow your business all run on a nervous system that must be regulated to perform at its best.
The Cost That Compounds Every Month
When you chronically override those signals, the dysregulation extends across the rest of your month. Your sleep suffers. Furthermore, your stress tolerance drops. Your output in the phases where you are naturally wired to perform, where estrogen is rising and cognitive sharpness is at its peak, gets blunted because you are still recovering from the week you refused to rest.
Pushing through is not ambition. Instead, it is a leak in your capacity that grows bigger every month you ignore it.
The Cycle Successful Women Were Never Taught
Here is the piece of information that reframes everything, and that almost no business or productivity content accounts for.
Men operate on a 24-hour hormonal cycle. Testosterone peaks in the morning, dips in the afternoon, and resets overnight. Every day is roughly the same. Consequently, the productivity frameworks, morning routine culture, and output-at-all-costs mentality were all built around that biology.
Women, however, operate on a 28-day cycle with four distinct phases, each with different cognitive strengths, energy levels, and recovery needs.
Menstrual phase (days 1 to 5): Estrogen and progesterone are at their lowest. The nervous system is more reactive. This phase calls for protection, not production.
Follicular phase (days 6 to 13): Estrogen begins rising. Energy, focus, and creativity increase. This is your natural window for strategic planning, new ideas, and high-output creative work.
Ovulatory phase (around day 14): Peak estrogen combines with a testosterone surge. Communication, confidence, and persuasion are at their highest. Therefore, this is the phase for sales conversations, launches, and big asks.
Luteal phase (days 15 to 28): Progesterone rises, then both hormones decline. Energy becomes more internal. This phase suits detail work, editing, systems, and reflection and toward the end, nervous system protection ahead of day one.
Just as different people need different amounts of sleep to feel rested, women are not designed to produce the same output every day. Expecting that of yourself is not a high standard. It is a mismatch between your biology and your demands.
What Changes When You Stop Refusing to See It
This is not about doing less. It is about doing the right things at the right times, which is in every other context exactly how successful women think about strategy.
Decision-making sharpens on high-capacity days, because you are not running on depletion from the days you did not protect. Creativity returns in the follicular and ovulatory phases, but only when you have recovered enough to access it. Sleep improves because a regulated nervous system can actually downregulate at night. Confidence stabilises because you stop losing whole weeks to recovery. And most importantly, your capacity for growth increases because capacity is built in recovery, not in output.
Every high-performance framework in sport and science agrees: adaptation happens in the rest, not the work. Your business is no different.
How to Start This Week
You do not need a hormone panel or a tracking app to begin working with your cycle. You simply need awareness and the willingness to act on what you notice.
Start here this week:
- Notice where you are in your cycle. Early, middle, or late is enough to start making smarter decisions.
- On higher-energy days, schedule the pitches, launches, strategic thinking, and hard conversations.
- On lower-energy days, schedule admin, behind-the-scenes work, or reflection. Rest if you can.
- When pain, fatigue, or brain fog show up, stop trying to override them. Ask what your nervous system needs and then give it that.
- Stop minimising your symptoms. Your pain is not an inconvenience. It is information.
Knowing that my first day requires rest does not make me a bad CEO. It makes me a smarter one. Successful women who are scaling sustainably, not burning out behind a polished Instagram grid, are the ones who figured this out first.
You are not broken. You are not weak. You are not a bad CEO because your body has a rhythm. You are a successful woman who has been operating on a model that was never designed for her biology.
Are you ready to stop letting the one thing you have been refusing to admit keep slowing you down?
Every week in Bubble Baths and Boundaries, I share honest stories, nervous system science, and practical strategies for ambitious women who are done white-knuckling their way to growth. If you want real content that helps you scale without burning out, join my email list.
