In the late 80s I stumbled across a movie called American Flyers; a cycling film that never quite got the audience it deserved but stuck with me for decades. Buried in the script was a line of Latin that I couldn’t shake:

Res firma mitescere nescit.

The film translates it loosely as “once you’ve got it up, keep it up.” Crude, funny, and oddly perfect for pushing through the last mile of a long ride.

I kept coming back to it. Through cycling, swimming, running, CrossFit — whenever the effort got hard and quitting felt reasonable, that phrase showed up. It wasn’t motivation exactly. It was more like a quiet reminder that resolve, once built, doesn’t have to be rebuilt from scratch every time.

Eventually I put it on a t-shirt. As you do.

But somewhere along the way I noticed the phrase had followed me off the bike. It applied to hard conversations, to leadership under pressure, to the slow work of recovering from burnout. A firm foundation doesn’t just help you finish races, it helps you stay standing when life gets complicated.

The more literal translation is: a firm resolve does not weaken.

Which turns out to be less about stubbornness and more about design. Building something in yourself that stress can test but not permanently diminish.

That’s what this is. A resource for the recover and the thrive — for anyone doing the quiet, serious work of becoming harder to knock down.

I hope it lands for you the way it landed for me.
