The rule compares ventures by their plausible long-term ceiling and the evidence that the founder can reach it. Current activity alone is not enough: a busy small business may still have a lower ceiling than a younger opportunity with proven global demand. Once one venture demonstrates both traction and a much larger expansion path, the founder concentrates time there and winds down lower-potential distractions. Entrepreneurial variety can then come from expanding the same core into new countries, routes, products, or partnerships rather than continually opening unrelated companies. Uertitt described making this choice when he concluded that even dominating the United Kingdom violin market would not create the scale available to Send My Bag, whose service could expand internationally.

Core principles
- 01Compare opportunity ceilings, not only current revenue
- 02Require evidence before concentrating
- 03Expand the winning core before starting unrelated ventures
- 04Use new markets to satisfy entrepreneurial range without losing focus
How to run it
- 1
Map the options
List each current venture and the realistic ways it could expand.
Pro tip Include geographic and product expansion within the existing winner.
- 2
Compare the ceilings
Estimate how large each opportunity could become if execution goes well, without treating aspiration as evidence.
Pro tip Use reachable customers, repeat demand, and market breadth rather than vanity market-size figures.
Watch out A large theoretical market does not compensate for absent demand.
- 3
Check the proof
Look for paying customers, repeat use, referrals, and signs the model travels into another market.
Pro tip Concentrate only after the opportunity has earned it.
- 4
Choose the core
Direct the majority of attention and resources to the proven opportunity with the strongest ceiling.
Pro tip Wind down lower-ceiling work cleanly instead of leaving it as a permanent distraction.
- 5
Expand without fragmenting
Channel new ideas into markets and services that advance the same core goal.
Pro tip Use country launches and adjacent offerings to create novelty without splitting the company.
Watch out Do not label every unrelated idea as an adjacency.
In the wild
Uertitt operated the music business alongside Send My Bag for several years. He eventually judged that selling every violin in the United Kingdom would still not match the worldwide potential of the luggage service. He wrapped up the music business and focused on establishing Send My Bag in markets including the United States and Australia.
→ His effort concentrated on one business with a global expansion path rather than remaining split across ventures.
Common mistakes
Choosing only by current busyness
A venture can consume substantial effort while still offering a comparatively limited ceiling.
Confusing possibility with proof
A global claim needs customer and execution evidence before it deserves concentrated resources.
Creating novelty through distraction
Starting unrelated ventures can fragment effort when the core still has attractive markets and services to open.
Is it for you?
Best for
It is best for founders splitting attention across several opportunities after one has begun to show meaningful traction.
Not ideal for
It is not ideal when market evidence is too weak to compare opportunities or when concentration would create unacceptable dependency.
From the transcript
“I could sell every violin in the UK next year and that ain't still going to be a massive business”
“I wanted us to be the semiag of America, the semiag of Australia and so on”
“I've not had that desire to get dragged into other things now”
