The investment that changed everything.

I am in my second year of coaching with a woman named Elizabeth. The investment has been real — in money, in time, and in the willingness to show up without knowing the answers.

That is what this requires. Showing up every other week to a 90-minute workshop where the subject is me. Virtual, in person, at mastermind retreats where the room is full of high performers and the only agenda is truth. There is no way to stay comfortable in it. That is exactly the point.

I remember arriving at a retreat on day two and standing up in front of the room to say something I had never said out loud before. I told them I had realized the night before that I was falling in love with myself. The room went quiet the way rooms do when something true has just landed. That moment lives in me. I return to it often.

What has come from showing up that way? The answers I am most proud of did not come from a boardroom or a spreadsheet. They came through during relaxation. One of them arrived in a session and has grown into something I believe could change an entire industry.

I run a multi-million dollar last-mile delivery company called Santosa Delivery. Workers' compensation claims and insurance costs are crushing logistics organizations across the country. I believe that a structured relaxation and intention-setting practice, delivered to drivers in two focused minutes, can reduce injury, improve decision-making, and change the trajectory of a person's day — and over time, their life. So I am building a program to prove it. Scientific methodology. Control groups. R&D tax credits funding the research. The kind of evidence base that lets this work stand in a boardroom, in an insurance conversation, in a courtroom if it ever needs to. If it works — and I believe it will — this becomes a company of its own.

That idea did not come to me at a strategy session. It came to me in stillness, under Elizabeth's tutelage, in a moment when I was finally quiet enough to hear it.

What would open in you if you stopped needing to have the answer before you walked into the room?

Last week I asked you to pick one thing. Here is your next one.

Keep the one you chose last week. Now add this:

The next layer: Dim every light in your home thirty minutes before you want to sleep. Overhead lights off. Lamps at their lowest. Every screen dimmed or closed. Your brain reads light as a signal — the most primal one it knows — and when the light drops, your melatonin rises and your nervous system begins its real recovery work. This single change, layered on top of what you chose last week, is when the compounding begins.

Next week: the layer that most people skip entirely, and the one the research says matters most.

Emily Weiss — the edit that made everything sharper.

You know her as the woman who turned a beauty blog into Glossier, a brand people tattooed on their arms and lined up around the block to enter. The part of her story that matters to Signal Edge readers is what happened after the hypergrowth years.

She stepped out of the CEO chair while the music was still playing. She moved into an executive chair role, had a child, and quietly reset the company around profitable stores and product discipline rather than the next funding headline. Most people called it a retreat. She understood it as a sharper operating principle. She noticed that the loudest version of success was producing diminishing returns for both the business and her life, and she made an edit.

She now operates more like a product editor than a showrunner, making fewer and cleaner bets that leave room for the rest of a life. The signal in her story is one I think about often. The moment you stop chasing the scoreboard and start picking the game you actually want to play is the moment your real edge begins.

The mouthwash signal.

Most of us have been using antibacterial mouthwash since we were teenagers, without questioning it. Here is what the research is starting to say: those bacteria you are killing? Your cardiovascular system depends on some of them.

Nitrate-reducing bacteria in the mouth convert dietary nitrates — from leafy greens, beets, cruciferous vegetables — into nitric oxide. Nitric oxide relaxes and dilates blood vessels, regulates blood pressure, and is essential for cardiovascular function. Antibacterial mouthwash does not distinguish between the bacteria it kills. It eliminates the nitrate reducers along with everything else.

A 2019 study in Free Radical Biology and Medicine found that two days of antibacterial mouthwash reduced nitric oxide levels by 25 percent and increased diastolic blood pressure measurably. Additional research has linked chronic antibacterial mouthwash use to a 55 percent higher pre-diabetes risk and an 85 percent increase in hypertension.

I am looking into alternatives. I will report back in the next issue with what I find and what I have decided to do about it.

This is not medical advice. Talk to your doctor before changing any health routine.

Two to add to your radar.

Stelo by Dexcom — the first over-the-counter continuous glucose monitor, available without a prescription at $55 a month. Its integration with Oura Ring means your metabolic and sleep data now speak to each other inside a single app. If you wear either device, this is worth researching.

Pulsetto — a vagus nerve stimulator delivering four-minute sessions that measurably reduce stress and improve heart rate variability. The nervous system category is expanding fast, and Pulsetto is one of the cleaner entry points into it.

The Roth conversion window.

If your income is lower in any given year — a transition year, an early retirement year, a year with significant deductions — you may be sitting inside a Roth conversion window without knowing it.

A Roth conversion moves money from a traditional IRA (pre-tax) to a Roth IRA (post-tax), triggering taxes now but eliminating them forever on all future growth and withdrawals. The ideal conversion happens in the years when your marginal tax rate is lower than you expect it to be in retirement. Every dollar converted in those windows grows tax-free for life and passes to your heirs without required distributions.

This is the kind of strategy your accountant should be modeling for you every year. If they are not bringing it up, ask. The window is not always open.

Please work with a qualified financial advisor on the specifics of your own situation.

Something worth sitting with this week.

The women in this community have built things that last. The signal this week is simpler than a strategy. It is a reminder that the discipline you applied to building — the consistency, the showing up, the long view — is exactly what health, relationships, and the second half of your life require too.

You already know how to build for the long game. You have been doing it. The same instinct that made you put money away before you spent it, that made you choose the unsexy decision over the flashy one — that instinct is still the edge. Apply it everywhere.

Twelve founding members in the first two weeks. Thirteen spots remain before Signal Edge becomes a paid subscription and the founding chapter closes.

If you have been thinking about forwarding this to someone, this is the week. The women who arrive at the beginning of something always help shape what it becomes.
