Look Before You Leap

The loop, planned backwards

Most people plan forwards: build this, then that, then launch. Winners plan backwards — starting from the one thing they need to learn.

The principle

Progress is laps of learning, not features shipped. You act Build → Measure → Learn, but you PLAN in reverse: decide what you must learn, then what you'd measure to know it, then the smallest thing to build. Then make every lap faster.

Plan the loop backwards
  1. Name what you must LEARN — e.g. 'will buyers pay 200 for this?'
  2. Decide what you'd MEASURE to know it — paid preorders, not likes or 'maybes.'
  3. Build the smallest thing that produces that measurement.
  4. Run the lap, read the data, and feed it into the next idea.
  5. Then attack the lap TIME — more at-bats per dollar beats one big polished swing.

A circular loop — ideas → build → product → measure → data → learn — with a stopwatch on the whole ring: minimize total time around it. Plan counter-clockwise, execute clockwise.
How the books connect

One owner spends six months building, measures once, then learns he was wrong — a single slow lap. Another runs six one-month laps and course-corrects five times. Same six months; only the second now knows the market cold.

Story

Michelangelo was asked how he carved David. The idea — 'remove everything that isn't David' — is the whole point: iteration is not a detour on the way to the work, it IS the work. Owners who treat every revision as proof they failed quit right before the statue appears.

Pitfall

Confusing motion with a loop. Building for six months without measuring is not one long lap — it's zero laps. You only learn when the loop closes on real data.

Takeaway

Don't measure yourself by what you've built; measure yourself by how many complete learning laps you've run — and spend your cleverness on making the next lap shorter.

📌 Do this Monday

Take your current plan and write the loop backwards on one line: 'To learn ___, I'll measure ___, by building ___.' Then ask how to run that loop in weeks, not months.
