The 90/10 rule. Perfection is killing you. Rhythm is begging you.

Here's how to come back to yourself.

One of my 10% nights. The win is what you return to next.

We’re a week into December.

If your rhythm slipped over the last week due to travel, guests, sugar, or late nights, you might be tempted to start over on Monday. Or in January.

Don’t fall for that. Don’t decide your rhythm is broken and torch your beautiful momentum.

Instead, pick up the 90/10 Rule. I use it in my own life. It dispels the unforgiving, unspoken notion that your nervous system needs perfection and supports what’s actually true: that it needs a stable place to return to.

Perfection kills rhythm

Rhythm builds trust. Trust sustains energy.

Here’s what perfection looks like:

• If I can’t keep it up, what’s the point?

• I had dessert at lunch. So I might as well keep going and start back on Monday.

• I missed my lunch window. This isn’t working for me right now, I’m just too busy.

• Travel blew my schedule. I’ll reset in January.

Perfection is fragile. One late meeting, one in-town guest, one holiday, and the perfect plan breaks. Along with it, self-trust.

The way my life is, with frequent travel, work projects, ongoing family demands, and all the holidays and milestones popping up throughout the year, one might say it’s smarter to just start over after “everything settles down.”

But that’s exactly how we lose a whole month we didn’t need to lose. And in some cases, entire life chapters. One woman told me: I figure I’ll just get to “me” after my kids leave home. Her youngest at the time was 5. Holy shit.

There’s something much more sustainable, and much more kind, than perfection. Rhythm.

Rhythm says:

• I chose my anchors once, and my job is to return to them.

• I flex 10% of the time, and I come home 90% of the time.

• The miss isn’t the problem. The delay in return is.

While perfection measures how long you can white-knuckle a streak, rhythm measures your return rate. Perfection is punishing, rhythm is forgiving.

The 90/10 Rule

When most people hear “90/10” they think it means 90% “good” food, 10% “bad” food. It’s not about that.

90/10 is about rhythm.

• 90% of the time you honor your anchors:
  your lunch window, warm food, simple movement, basic bedtime.

• 10% of the time life happens:
  late dinners, travel, parties, takeout, weird timing, zero cooking.

The win isn’t zero 10% days, never eating dessert, or never missing your perfect” window. That would be rigidity. The win is: I can have a 10% day and still trust myself to come back to my 90% at the next possible meal.

The win is sovereignty. You make the decision once, and you keep returning to it instead of renegotiating your life at every fork in the road.

Your anchor is the point.

Let’s start with the lunch anchor, because lunch is where so many of us lose the day.

Say your anchor is an 11:45–12:15 warm lunch.

On a 90% day, this might look like

• Simple kitchari or lentil soup you made once and reheated

• Warm leftovers from last night’s real food

• A quick sauté of veggies + egg + rice

On a 10% day, it might look like

• Lunch at 2:30 after a back-to-back meeting block

• Airport food at a weird hour

• Chips and dip before a holiday party because you never actually stopped to eat

• Oops, lunch was coffee and a cookie

Here’s where perfection and rhythm think differently:

Perfection brain

• I blew it.

• I’ll skip dinner / I’ll only have salad / I’ll restart on Monday / I need a full reset.

Rhythm brain (90/10)

• Okay, that was my 10%. I’ll drop into my next anchor.

Maybe dinner can’t be at your exact ideal time because life.
That happens to me quite often. Fine. But I can still protect something.

• A warm plate instead of cold grazing

• A set window instead of whenever

• Sitting down instead of hovering over the sink

Instead of punishing the miss, shorten the distance between the miss and the return. Because that distance is where exhaustion, bloating, and self-doubt live.

How to use 90/10 this week

Don’t wait until next month. Use this rule right now, inside the swirl of the holidays or other life’s demands.

1. Decide your 90% anchors

Keep it simple. Choose 2–3 anchors, not 17.

Examples:

• Warm Lunch: 11:45–12:15

• Evening: screens off by 8:30, in bed by 10.

• Movement: 10–20 minutes of walking or stretching in the early morning (or mid-afternoon)

Write them down. These are your home base. Instead of trying to hit them perfectly, promise to return to them.

2. Name your 10% ahead of time

Look at the next 7 days.

Where do you already know rhythm will bend?

• Holiday party Thursday night

• Travel day next weekend

• Big project deadline mid-week

• Kids’ event at dinner time

Mark those as your likely 10% pockets. Now, instead of failing, you’re choosing: These are the days where I’ll flex. I’m committed to coming back to my very next anchor.

3. When you slip, ask only this:

At the first moment you notice you’re off, whether it’s 3 pm chocolate, a skipped lunch, or too much snacking, pause and ask: What’s the very next anchor I can return to?

• If lunch went off the rails, protect your afternoon walk. Or dinner.

• If dinner was chaos, protect your morning practice. Or tomorrow’s warm, on-time lunch.

• If today is gone, protect tomorrow’s first anchor on your list.

Then follow through. Your quick return reactivates your self-trust far more than a perfect week that you can’t sustain.

What sovereignty looks like

• I decided what supports my body.

• I gave that decision a shape: time, temperature, and simplicity.

• I fully expect life to be 10% messy.

• I trust myself to come home 90% of the time.

You hold the design. And when you hold it, your body feels it:

• Less 3 pm crash

• Fewer ‘I’m so behind’ spirals

• Clearer decisions because your blood sugar isn’t screaming over your intuition

• A quiet sense of I can count on myself

Try this for the next 7 days

1. Pick your 2–3 anchors.
   If you choose nothing else, choose your warm, on-time lunch window. Ideally between 10am and done by 2pm when digestion is strongest.

2. Circle your likely 10% days.
   Parties, travel, deadlines. Mark them without drama, without narrative.

3. When you slip, shorten the distance.
   Ask: “What anchor can come back to next?” Then come back.

4. At the end of the week, review:

   • How many times did I return?

   • How did my afternoons feel?

   • How did my sleep feel?

Grade yourself on your return rate. Because your rhythm just needs you to come home.

Eat warm, breathe slow, keep a rhythm
