On twelve shoe saleswomen in six minutes, overcoming body shame in the sauna, and dancing with your eyes closed

I thought it would be a quiet week. It wasn’t. Performed on stage as a shoe saleswoman with twelve faces, went to the sauna solo for the first time, slept twelve hours after nine months of building, a…

About saying no during Pentecost, 50 singing men in a warehouse, and the price of fame

Pentecost weekend. Everyone out on boats, terraces, soaking up the sun. Me? Working on my training sixteen hours a day. No to the boat. No to the terrace. No to “let’s quickly visit a market.” James C…

On Jimmy in the mud, a training turned upside down, and the Luxor Theater

I almost skipped this week. Too busy. Restructured my whole training. Easy excuse. But James Clear wrote: “The issue isn’t skipping once. It’s that you practice being someone who skips.” So here’s pea…

On nearly throwing up at the printer, 40 weeks of showing up, and tears near the water

Number 40. Forty weeks of showing up. Every single week. Not perfect. But 40 pearls on the string, turds and all. And what a week. I was on stage at the Shadow Summit alongside Barry Michels. I nearly…

    Two years. Blood, sweat and tears. A gazillion messages with my illustrator. Three test prints because the paper didn’t shuffle right. But it’s here. The State Shift Method® is now available for pr…

  • On saying no, letting go of boxes, and why vulnerability is the glue

    Last time I moved with two full cars. This time? Four. My friend called me out: “Holtslag, what happened?” So this week: saying no. No to events. No to stuff. Five boxes out the door. Also in Peek in…

  • About questions that aren’t in the books, going out without alcohol, and why perfection is overrated

  • Full moon dip, a wildly important goal, and stopping as a strategy.

    Last week, for the first time ever: a full moon dip. The water was something else. Just like this: “One is not born a woman. One becomes one.” Maybe that applies to more than you think. Peek in my Wee…

  • About being fit for the job, sending love, and why EPiC truly lives up to its name.

    Hermit mode in sweatpants and bathrobe. Until I swapped them for my seventies flares and headed to the cinema. Elvis EPiC. 8.5 on IMDb. Oh boy, was I glad that I did. Plus: why inner work is never don…

  • The world needs you. Just not the way you think.

    You worry about all the misery in the world. Meanwhile at home you snap at the people closest to you or stop communicating altogether. Michael Singer puts it like this: you are creating a war right no…

  • On hermit mode, a ring the universe took back, and the excuses of your inner saboteur
