My daughter asked me something this morning that stopped me in my tracks.
“Dad, why don’t you ever get mad?”
I smiled. Because the honest answer is — I do. I get frustrated. I feel everything. But somewhere between 11 years working with astronauts and leaders at NASA, and four months of the most personally meaningful work of my life, I learned something that changed how I move through the world.
There is a space between what happens to you and how you respond.
That space is everything.
Psychology calls it response inhibition. High performers call it composure. Scripture calls it being slow to anger. And for the past four months, I’ve been building a daily practice around it — one devotion, one breath, one rep at a time.
Today, I get to share it with you.
The ONE App — a daily devotional for high performers — has officially been approved by Apple and is live today.
This isn’t a productivity app. It isn’t a meditation app. It’s a training ground for the one skill that separates elite performers from everyone else: the ability to create stillness and space under pressure, on demand.
I built this for the golfer who performs beautifully in practice but falls apart on the back nine. For the busy parent who snaps before they mean to. For the driven professional who knows their mind is the ceiling — and wants to raise it. For anyone who has ever wished they could respond instead of react.
This is the same mental framework I developed at NASA. The same principles I’ve brought to elite junior golfers, collegiate athletes, and LPGA Tour players through MPGA. Distilled into a daily practice you can begin right now.
A book is also coming — integrating high-performance psychology, golf performance, and the spiritual foundation that holds all of it together. This is a journey I’ve been on for years, and I can’t wait to bring you into it fully.
But it starts today. With one moment of stillness.
Stillness isn’t a personality trait. It’s a practice. And you can start building it right now.

If you do download the app and play around with it. I have one favor to ask… could you give us a review on the app store? It would mean the world to me.
Thank you.
