from Kim, once a week

↓ on running your coaching business with less friction

Room to Breathe.

A weekly letter for coaches building something real. One honest story, one idea you can steal, and a nerdy fact you didn't know you needed.

Most Sundays. Sometimes Monday morning, if the week ran long.

What this actually is

The letter I wish someone had sent me

KC
Kim Curtis
Founder at Sidkik

Once a week I write down what is actually going on... the story, the thing I am figuring out, and one small move you can steal. It reads like a long note from a friend who happens to be building your software and has spent over 25 years in operations. No funnel. No pitch. Just a few honest minutes. And yes, it is for coaches... and for the OBMs and tech folks who quietly keep them running.

Inside every issue
A story from the trenches

What is actually happening while I build Sidkik and live a real life. Sixty days heads-down. A demo that bombed. A knee that finally stopped hurting. The real version, not the highlight reel.

One idea you can steal

Every story lands on a single, usable move. "Borrowed claims vs. real claims" on your time. "Transformation is a millimeter you cannot feel." Named so it sticks, small enough to try this week.

A random fact... to learn something new 

The P.S. people write back about. A true, delightfully useless fact tied to the week's topic, usually one Wikipedia rabbit hole deep. Ask me about the day the clocks jumped to match the trains.

Who owns the clock?

"Sixty days straight, zero off, and..."

The idea

Sort every demand on your time into real claims and borrowed ones. Then hand the borrowed ones back.

For the nerds

Until 1883, every town set its own clock by the sun. Then the railroads forced a single time, and clocks jumped overnight.

A Year of Millimeters

"A year ago, I couldn't stand up..."

The idea

Don't wait for the leap. Show up to your operations a millimeter at a time, and back off on the hard days.

For the nerds

Your cartilage has no blood supply. It is fed only when you move, so showing up, even barely, is never wasted.

Version Five

"Decades in usability, and on..."

The idea

The product you love wasn't genius, it was iteration. On version five and still bumpy means you're right on track.

For the nerds

WD-40 is named for the 40th formula. The first 39 attempts failed, so the brand is basically a monument to 39 flops.
