How it works

Question → Test → Decide → Learn

See the method on a real decision: start from what could go wrong and work back to your safest next move.

Illustrative decision: Should I leave my job to start a business?

Today · the default
“If I go all in, customers will follow.”
Six months later · the worst case

You quit, the sales don't come, and your savings run out in six months.

Rewind: 4 checks that could have prevented it

  1. 01 · Question

    What could go wrong?

    What has to be true for this to work? Will people actually pay money, or are they just being polite?

  2. 02 · Test

    What's the cheapest check?

    Run a small paid pilot, pre-sale page or direct offer while you still have your job.

  3. 03 · Decide

    What's the smallest safe step?

    Leave only once you hit a real sales target and have six months' cash buffer.

  4. 04 · Learn

    What will I check next time?

    Compare real paid demand with what you expected, then adjust your offer.
