Goggins keeps a jar of memories for exactly one purpose
In *Can't Hurt Me*, David Goggins describes a mental trick built from his own worst years, not his best ones.
Before David Goggins became a Navy SEAL, he was overweight, working a pest-control job, and had already failed the SEAL screening once. He calls the collection of everything he survived before that point his cookie jar: specific, named memories of moments he thought he couldn't continue and did anyway, stored away rather than left as vague self-belief.
He describes reaching into that jar mid-race, when a hundred miles in his body is done arguing and just refusing. Not a pep talk. A named memory, retrieved on purpose. Something like the exact night he studied for a test he'd been told he couldn't pass, replayed until the current mile becomes survivable by comparison.
The idea reframes what a hard memory is for. Most people file suffering away to avoid it. Goggins treats his as inventory, cataloged and specific enough to retrieve on demand, because a vague sense that you're resilient doesn't hold up at hour eighteen. A remembered Tuesday does. The jar only works if what's inside it actually happened to you.
