You know the difference when you see it. Two people in roughly the same circumstances. One makes things happen. The other has ideas, opinions, and explanations for why things didn't.
The difference isn't intelligence. It isn't luck. It's a trait Tyler Cowen and others have called high agency — the disposition to treat obstacles as puzzles to solve rather than reasons to stop.
Nine principles
1. Default to action
Most decisions are reversible. Most problems get smaller once you start on them. The bias toward waiting feels responsible — it usually isn't. Do the thing. Learn from the thing. Adjust.
2. Take full ownership
Even when it isn't fully your fault, treat it as fully your problem. The mental weight of "whose fault is this" is paid in the currency of your time, which is the only currency that matters.
3. Make the call
Indecision is a decision — to stay where you are. High-agency people make calls faster than comfortable, because they know they can course-correct later. The cost of a wrong call is almost always lower than the cost of no call.
4. Talk to the person who can help
You are two emails away from almost everyone you'd benefit from knowing. The reason most people don't reach out is that it feels awkward. Awkwardness is a small price for a skipped year of figuring it out alone.
5. Keep scope ruthless
Ambitious goals, minimal scope. Half the battle is cutting what doesn't matter, not adding what does. A smaller, finished thing beats a larger, unfinished one every single time.
6. Respect momentum
Momentum is fragile and expensive to rebuild. When you have it, protect it. When you don't, the fastest way to get it back is a tiny win — one phone call, one paragraph, one completed thing that moves the needle.
7. Be willing to be wrong in public
The fastest feedback comes from putting things in front of people before they're ready. Yes, it's uncomfortable. Yes, you'll get corrected. That's the point. The corrections compound. The discomfort fades.
8. Finish what you start
Finishing is a muscle. Each time you finish a thing, the muscle gets stronger and the psychological weight of your open loops gets lighter. Each time you abandon a thing, the reverse happens. Be careful what you start.
9. Treat time as the non-renewable resource it is
Everything else — money, status, relationships, skills — can be rebuilt. Time can't. The people who get an outsized amount done in a life are the ones who have internalized this at a cellular level. They're not working harder. They're deciding faster about where their hours go.
None of this is mystical. Agency is a practice, and practices get stronger with repetition. The first step is noticing where you're not exercising it — and doing the small uncomfortable thing that moves you forward anyway.
