The aiming diagram.
Drag your position on the timeline and watch predictability, your arrow, the baby's arrow, the hedge, and the retraining cost curve recalculate. Below: when each compounding skill pays off across a lifespan.
What the diagram carries
- Your arrow
A near target, about five years out
Close enough that your current moat still reaches it. Far enough that it is not just today's job with a new label.
- Baby's arrow
A far target, about fifteen years out
A newborn has twenty years of runway, so the far target is cheap to aim at — but it sits deep in the unpredictable zone, where almost nothing is knowable yet.
- Feedback loop
Skills compound; predictability moves with you
Practice produces judgment; judgment produces better practice. Your personal predictable zone creeps forward even as the world's decays.
- Moat
Your current position constrains the reachable set
A designer aiming at AI-assisted design has a shorter, more reliable arrow than one aiming at pure engineering. Not every future is in range from where you stand.
- Split arrow
Primary bet plus a dashed hedge
With a short runway you cannot afford one wrong bet. Keep two arrows alive: one solid commitment, one dashed option that costs little to maintain.
- Cost curve
Retraining is not linear
Year one of learning something new is cheap. Year three is expensive. Past a point you are not upskilling — you are starting over.
When each skill pays off
The eight compounding skills are not equally urgent at every age. Each one has a window where it compounds hardest — and a cost to starting late.
Meta-learning & taste
The cheapest years to learn how to learn, and the most formative for taste — every project recalibrates what you notice. Starting late here means relearning the habit of learning.
Judgment & writing
Judgment compounds from the first decision you own; writing compounds from the first piece you publish. Both need volume, and volume needs runway. This is the window where the cost curve is still flat.
Distribution & relationships
Audience and trust take a decade to build and cannot be rushed. This is when the moat is deepest — and when the hedge matters most, because one wrong bet costs the most.
Teaching & systems thinking
Teaching forces mastery and builds the tribe at the same time. Systems thinking tells you where the arrow lands. Both pay off hardest when you have something worth explaining.
Meta-learning again
The only skill with no expiry. It makes every other skill cheaper to acquire — which is why it belongs on every card, not just the first.
The diagram is the frame
The eight compounding skills are the content inside it — each one is a way of aiming the arrow or pulling the predictable band forward.
Compounding skills
Judgment, taste, distribution, teaching, systems thinking, writing, relationships, meta-learning — ranked by how much they multiply.
Line 01Made by human is the new luxury
Authorship, answerability, local cost — what stays expensive when fluent output is free.
Line 02Tribe building is the next big thing
A boundary, a shared task, a memory, an exit — obligation does not scale like output does.
